The coming of the 10 millionth car in the Automotive industry symbolize that Chine have stepped in a high level in this filed. However, China have not take a strong point while enlarging the market. And the auto parts tend to bring more convinent for the people’s life, and they are also commonly used by the people who own cars. The inverters in the maket are with mixed failure. The disadvantages of traditional ones is obviously, which are inefficient, nosiy and with modified sine wave output. They show many technological disadvantages. However, the inverters we need today have to be with high quality of AC power outlet, and also have to be smarter and lighter.
The orginal function of the auto inverters is supplying power for the devices in the car, thus the output of the inverter have to fit for the devices, so we need to make the inverter output sine wave with enough power to supply most of the devices.
This report introduce the Concepts, definitions, classification and production of the inverter. We do many reserches, designs on the basis of the professional knowledge and limit data, trying to make a feasible pure sine wave ivverter power and then test it.
Keywords: Inverter Power，Pure sine wave，Pwm wave technology.
