Power converters and power inverters are two different types of power conversion equipment. 1. Power Converter: A power converter is a device that converts electrical energy from one form to another. It can convert alternating current to direct current, or convert direct current to alternating current. Common power converters include power adapter, power transformers, etc. Power converters are often used to convert grid voltage to a voltage suitable for use by electronic devices, or to convert DC power from a battery to AC power. 2. Power Inverter: A power inverter is a device that converts DC power into AC power. It converts DC power into AC power so that DC power can be supplied to AC equipment. Power inverters are usually used in solar power generation systems, automotive electronic equipment, emergency power supplies, etc. to convert DC power into AC power. The main differences are as follows: Working principle: The power converter uses the working principle of a transformer to achieve the conversion of electrical energy by changing the voltage ratio of the input power supply and the output power supply, and the power conversion efficiency is high. The power inverter converts DC power into AC power through the working principle of high-frequency active switches and inverter transformers, and the conversion power efficiency is low. Control method: Power converters generally use pulse width modulation control to control the output voltage and current by controlling the switching frequency and duty cycle of the switching device. Power inverters generally use PWM modulation and closed-loop control methods to control the frequency and amplitude of the output AC voltage by adjusting the switching frequency and duty cycle. Equipment structure: The power converter is relatively simple and consists of a few components; the power inverter requires more complex components and circuit structure because it needs to convert DC to AC. Scope of application: Power converters are mainly used in power electronic equipment, communication equipment, electronic equipment and other occasions to convert input power into the voltage and current required by the equipment. Power inverters are mainly used in solar power generation, electric vehicles, UPS power supply and other fields to convert DC power into AC power supply, such as car chargers. A power converter is a device that converts electrical energy from one form to another, while a power inverter is a device that converts direct current into alternating current.

A Power Charger is a device used to convert the power supply voltage into a voltage suitable for charging equipment, and transfer electrical energy to the charging equipment through current transmission to charge or power it. Chargers are commonly used to charge mobile devices (such as mobile phones, tablets, laptops, etc.) and can also be used to charge other types of electronic devices (such as cameras, Bluetooth headsets, power tools, etc.). A charger usually consists of a plug (for plugging into a power outlet), a converter (for converting the mains voltage to a voltage suitable for the charging device), and a connector (for connecting the charger to the charging device). The working principle of the charger is relatively simple and is mainly divided into two steps: voltage transformation and rectification. First of all, the normal power output is AC power, and the device requires DC power, so the charger needs to convert AC power into DC power. This step is voltage transformation, which is achieved by converting the input transformer. The transformer contains a magnetic coil. When the input terminal is affected by alternating current, the magnetic coil produces a magnetic field, which in turn generates a current at the output terminal. By adjusting the ratio of the turns of the input and output coils, the output voltage can be controlled. The next step is rectification, which converts the AC power into DC power. This step requires the use of a rectifier circuit to convert alternating current into current flowing in only one direction in order to power the device. With the continuous advancement of technology and the increase in people's demand for mobile devices, the types of power chargers are becoming more and more abundant. There are many different types of chargers on the market today, such as traditional wall chargers, USB interface chargers, Car Chargers, Portable Charger, etc. These chargers come in different forms, but the principles and functions are roughly the same. Among them, USB Chargers have become mainstream because they are portable and can be used for a variety of devices. All in all, a power charger is a device that converts alternating current into direct current required by the device, through the steps of voltage transformation and rectification. It is an integral part of modern life, providing continuous and stable power to our electronic devices. Therefore, we need to use and maintain the charger correctly to ensure safe use and extend service life.

Before understanding automotive inverters, it is important to understand the difference between AC and DC power sources. In basic terms, AC power is what you get out of your home's electrical outlet, and DC power is what you get from a battery. Since car batteries provide DC voltage, but most consumer electronics use AC power, if you want to use AC equipment on the road, you need a device called a car power inverter. With a car power inverter installed, you can plug any electronic device, plug it into the car, and use it normally, with a few caveats. Some of the most important limiting factors to keep in mind when using an inverter in a car include the capacity of the car battery, the rated output of the alternator and the output power of the inverter. How does an inverter work? Inverters work by simulating alternating current (AC) power using a unidirectional DC power source. Electronic inverters are essentially oscillators that rapidly switch the polarity of the DC power supply, which effectively produces a square wave. Since most consumer electronics products require functionality closer to a true sine wave, most inverters contain additional components that produce a modified or pure sine wave. When do you need a car inverter? People who spend a lot of time on the road need inverters. These units are particularly useful for long-distance travel, camping, business travelers, off-road truck drivers, and other similar applications. Some devices, such as cell phones and laptops, can be used with 12v accessories that plug directly into the cigarette lighter or accessory jack. However, any electronic device that requires AC input requires an inverter. Some of the devices you can run with a car inverter include: TVs, DVD and Blu-ray players, computers, heaters, cooking equipment, power tools. What types of car inverters are there? There are many different types of inverters mainly: modified sine wave These inverters are the more affordable of the two. The "modified sine waves" they produce are fine for most consumer electronics, so they work well in many different applications. pure sine wave These tend to be more expensive, but they produce a sine wave that is closer to the AC power at your home's electrical outlet. Some devices, like uninterruptible power supplies, may not function properly without a steady, pure sine wave, but most consumer electronics will work fine without a power source.

Why do I need a WiFi repeater? The wireless repeater is designed to extend the range of the current wireless network and increase the coverage, allowing you to roam freely and access the Internet anywhere in your home. 1. Traditional routers cannot cover all places where wifi is used. 2. Villas or large houses/buildings cannot cover the use of wifi in all places. 3. The building wall is very thick, wifi cannot pass through. WiFi has entered the homes of ordinary people, and you can connect to the Internet wirelessly by picking up your mobile phone. However, there are always some corners and corners that cannot be covered by wireless. When you are grabbing red envelopes, when you are using Douyin, when you are really chatting with voice and video, wireless WiFi coverage is not wide, and sometimes it is very inconvenient and I want to add a new one. Is your router really just fine? In fact, it is also a very good choice to choose a wireless repeater to ensure wireless coverage. The wireless signal is used to spread the existing wireless signal through the repeater to expand the wireless network coverage area and make the wireless coverage wider.

The car inverter is a kind of power converter that can convert 12V direct current into 220V alternating current which is the same as the mains power for general electrical appliances. From the output waveform, the car inverter can be divided into sine wave output and square wave output. The former output is the same sine wave alternating current as the grid we use daily, which can adapt to various loads, but the circuit structure is more complicated and the volume is larger. The latter circuit is simple, but it is picky about the load and cannot drive inductive loads. Combining the advantages of the two, the current commercial vehicle inverters without exception have adopted the scheme of outputting an analog sine wave. Compared with the square wave, the use effect has been improved. It can not only drive inductive loads, but also has a small size and weight. Lightweight, high conversion efficiency, stable output voltage, strong reliability, and perfect protection functions. How should we choose a good car inverter? 1. Choose a metal shell inverter: The car inverter is more likely to generate heat due to its large power. If the internal heat cannot be dissipated in time, it will affect the life of the components, and in the worst case, a fire will occur. On the one hand, the metal shell has good heat dissipation characteristics, and on the other hand, it also avoids the risk of fire. 2. In the case of products with the same power and similar size, the heavier one is preferred: the heavier product weight means that the outer shell is thicker, which is good for heat dissipation. It also means that the internal transformer has high power and can drive high-power loads for a long time. 3. Perfect protection function: A good car inverter should have perfect protection function. It can protect your car and power supply under various conditions. It should also have sound and light alarm function to remind you to This situation is dealt with in a timely manner. Generally, the protection functions that should be possessed are input under-voltage protection, over-voltage protection, over-temperature protection, output overload protection, and output short-circuit protection. 4. Conversion efficiency: Conversion efficiency is a very important indicator of the inverter. The higher the inverter efficiency, the longer the battery is used, and the less the inverter generates heat. Generally, it should reach more than 90%. 5. Pay attention to the form of the output socket: it is necessary to be able to use the two-phase and three-phase plugs of the national standard.
