Abstract

The development of power electronic devices is relatively slow. As a result, the development of the high-frequency inverter is extremely limited. This paper analyzes the characteristics of the IGBT and MSP430 and then designs a high-frequency inverter control circuit based on MSP430. The PWM control wave is outputted in software by MSP430, and the PWM wave is amplified by the driver circuit for driving the half-bridge inverter main circuit made up of two IGBT components. Controllability includes adjustable frequency, variable duty cycle and dead time variable and several other aspects of PWM waves. This design realizes reducing losses and improving the efficiency of the overall circuit purposes. Meanwhile, the other circuit configuration such as driver and protection circuits in the entire system are also made some corresponding design description. Finally, the design of the control system is made further verification by IAR software download debugging. The final results prove that PWM control circuit based on drive and protection circuits can work and the frequency, duty cycle, dead time of the PWM can be adjusted. A brief analysis about the advantages and disadvantages of the entire circuit is reported and some improved methods are also presented at the end of this paper.
