Abstract :
This paper firstly used bipolar SPWM waveform generation method (regular sampling method) to generate waveform, and analyzed the harmonic wave of output voltage to design filter parameters accordingly, taking into account the dead-zone effect of the harmonic effects. Then it used current inner loop and voltage outer loop control strategy, using pole placement to design controller parameters, and joined the dead-time compensation. Finally it verified by simulation results.
