1. The principle of home inverter is based on practical use.
If you are a home lighting application, or a small commercial lighting at night, this load can be used for resistive loads (such as incandescent bulbs) with a non-sinusoidal inverter
2. If there are fans, blower and other inductive loads (such as electric motors), then sinusoidal inverter can be built. The prices of the two inverters vary greatly.
3. If the 1000 VA on the inverter is its power standard, then the inverter of this standard is an industrial-grade inverter, which can be used for communication base station and equipment room. The stable type is higher, but the efficiency is not as high as that of the high-frequency sinusoidal transformer.
4. The home inverter converts the dc power supply (battery, battery) into the transaction current (usually 220 V, 50 Hz sine wave). It consists of 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 inverters to connect battery-powered appliances and various tools for work.
The power specifications of the car inverter output through the lighter are 20W, 40W, 80W, 120W to 150w.
