The Study Of The High-output-frequency Resonant Pole Soft-Switching Inverter

On the basic of one kind of succinct novel main circuit for resonant-pole soft-switching which was proposed by the research and development topic group of inverter, this paper has designed the control circuit for the high frequency resonant soft-switching inverter which has taken TMS320F240 DSP as the core, and unifies own characteristic for controlling, has designed corresponding control software, has realized the basic function, and the auxiliary function of soft-switching inverter, has developed a principle prototype of inverter which switching- frequency is 40KHz, output- frequency is 2500Hz, and carried on the test to it, the experimental result has verified the circuits topologies working for the inverter with high-output frequency. According to the present literature retrieval, the technical specification of this inverter tracked the level of international , in the same way, it has not seen the related report in our country.Finally, this article thorough discussion the question which met in the design process, has produced the solution measure.
