60W逆变器设计

AbstractWith the progress of science and technology,inverter technology has been rapiddevelopment.Inverter is a kind of application of power semiconductor devices,whichcan transform into a DC power converter equipment AC power for AC load use.Therefore,the inverter technology has a very important position in the field ofdevelopment and application.This design is based on car inverter,systematically expounds the background ofvehicle-mounted inverter technology,the current situation of the development,thedesign process and a wide range of applications.The core of the inverter controlcircuit adopted TL494CN chip,and the high frequency transformer is used in thecircuit,greatly reduces the cost and volume of the inverter and gradually improve theperformance of the inverter.The inverter circuit of the input 12 V DC by twicefrequency conversion into 220 V /50 Hz alternating current output,with theinput/output overvoltage protection,and overheating protection function.Keywords:Vehicle-mounted inverter;High-frequency transformer;TL494CNI
