| Abstract: | The multiple structure of three-level inverter is presented to satisfy the requirement of large current and quick control for the fast control power supply in the EAST tokomak, which applies carrier phase-shift PWM technology to realize multi-inverters parallel. The design scheme is analyzed, and the output harmonic characteristic of parallel inverters is studied, the analytic expression of harmonic of the output voltage is obtained by means of dual Fourier transformation. The simulation and experimental results confirm that the power supply system has a perfect performance on harmonic feature, can supply large current and has ability of fast response. |
