研究目的
Implementation of a high efficient soft switched Snubber Assisted Zero Voltage and Zero Current (SAZZ) converter topology, integrated with a photovoltaic source, to power a three-phase Induction motor through three-phase inverter.
研究成果
A soft switched based, high efficient Sazz boost converter is utilized to maintain the DC- link voltage necessary to drive an 4 kW, 400V Induction motor powered from Sun energy. The recommended system uses variable frequency controlled SPWM, to maintain the constant speed at changing loads. The overall better performance of the recommended soft switched converter is proved, on comparing with the performance of Boost converter, both in transient and steady-state conditions.
