Inverter control circuit design
[ABSTRACT]: Inverter is a broader use of power, will enter through the exchange for DC rectifier, inverter for the exchange to work the way. Control is convenient, easy to improve the power supply frequency, reducing the size of the merits of power. This paper square on PWM inverter power control circuit, and analysis of PWM square wave power inverter principle.
According to this paper at the same time PWM square wave inverter features, a soft-switch technology, the design of the inverter prototype of the simulation system. The system includes the main circuit, control circuits, and protection, drive circuit, of which some of the main control circuit design. Finally in PSPICE software simulation, the simulation results are given, the simulation results show that the system is operating well, to complete the design tasks and for the future laid the foundation for the study.
