The PSIM(Power SIMulation) platform, due to the unique advantages, can complete analogy simulation, digital(hardware) simulation and C code generation of control program, that can solve the problem that puzzles researchers to deal with control program programming. The research, which is about the performance of single-phase H-bridge inverters, is carried out by using PSIM platform and experimental setup. This paper takes single-phase H-bridge inverter circuit as the research object. Firstly, the performance of SVPWM(Space Vector Pulse Width Modulation) has been researched for the single-phase H bridge inverter circuit by a detailed mathematical analysis for the three-level SVPWM algorithm in order to compare the traditional sinusoidal pulse width modulation(SPWM). Secondly the C code generated by PSIM is downloaded directly to the digital signal processing chip. Finally, the object experiment is analyzed using the DSP(Digital Signal Processor) experimental platform based on TMS320 F28335 controller. The comparative analysis shows that SVPWM technology has obvious superior performance compared with SPWM technology. Meanwhile, it also shows the superiority of using PSIM to do research.
