PWM Control for Actively Clamped Resonant DC-Link Inverter on Soft-Switching

Abstract:

Due to the active inverter in industrial application, if use hard switching mode, not only may have the switch losses, but also may produce electromagnetic interference and harmonic, these power quality is affected. This paper presents the design of a soft-switching active inverter, that active clamped resonant DC-link inverter topology was used on the main circuit, the voltage space vector pulse width modulation (SVPWM) control mode was used on control circuit, using TMS320LF2407DSP programming, while the AT89C51 was responsible for liquid crystal display task, data exchanged and coordinated between double CPU. The experimental results show that, the device switching-losses can effectively reduce, the switching frequency can improve, input power quality can improve.
