An power inverter is a device that converts a dc power supply (battery, battery) into a transaction current (usually 220 V, 50 Hz sine wave). It consists of power inverter bridge, control logic and filter circuit. Widely used in air conditioning, home theater, electric grinding wheel, power tools, sewing machine, DVD, VCD, computer, television, washing machine, lampblack machine, refrigerator, video recorder, masseuse, fan, lighting and other industries. In foreign countries, due to the high popularity of cars for work or travel, you can use power inverters to connect battery-powered appliances and various tools for work. The power specifications of the car power inverter output through the lighter are 20W, 40W, 80W, 120W to 150w. More power inverters must be connected to the battery via cables.
The DC to AC power inverter, which is actually a process of a voltage power inverter with a frequency converter. The power inverter converts the ac voltage of the grid to a stable 12V dc output, and the power inverter converts the 12V dc output of the adapter to high-frequency high-voltage ac. These two parts also use pulse width modulation (PWM) technology, which has been widely used. The core part of the controller is PWM integrated controller. The adapter adopts UC 3842, power inverter and TL 5001 chip. The operating voltage range of TL 5001 is 3. 6≤40V, pulse width modulation generator with error amplifier, voltage stabilizer, oscillator, dead zone control, low voltage protection circuit and short circuit protection circuit.
An power inverter converts a dc power supply (battery, battery) into a transaction current (usually 220 v50HZ sine wave or square wave). Generally speaking, an power inverter is a device that converts a direct current (DC) into an AC (AC). It consists of power inverter bridge, control logic and filter circuit. Widely used in air conditioning, home theater, electric grinding wheel, power tools, sewing machine, DVD, VCD, computer, television, washing machine, lampblack machine, refrigerator, video recorder, masseuse, fan, lighting and other industries.
Simply put, an power inverter is an electronic device that converts a low voltage (12 or 24 volts or 48 volts) from a direct current to an alternating current of 220 volts. We got the name because we normally convert a 220 volt ac rectifier to direct current, whereas an power inverter does the exact opposite. We are in the mobile age, mobile office, mobile communication, mobile leisure and entertainment. When in motion, people need not only low-voltage dc power supply powered by batteries or batteries, but also 220v ac power supply, which is essential for our daily environment. Inverter can meet our needs.
The power inverter itself consumes part of the power, so the input power is greater than the output power. The efficiency of the power inverter is the ratio of the output power to the input power of the power inverter, that is, the efficiency of the power inverter is the input power of the output power ratio. If the power inverter inputs 100 watts of direct current and outputs 90 watts of alternating current, its efficiency is 90%.
