DC/AC rely on the application of power semiconductor devices is to direct current to a change in the flow of electrical energy conversion devices exchange for sharing load electricity use. Therefore, rely on the development and use of technology in areas of extremely important position.
The inverter technology is one kind of very effective electrical energy transformation technology. This topic for the inverter, systematically elaborated the SPWM inversion power source present situation, the development, the manufacture process and the application. Used chip SG3524 and ICL8038 constituted the inverter core control circuit, final output 220V/50Hz alternating current.
