摘要: A single-ended primary-inductor converter (SEPIC) features low input current ripple and output voltage up/down capability. However, the switching devices in a two-level SEPIC suffer from high stresses losses. To cope with this drawback, study proposes three-level that uses voltage-rated switch thus achieves better performance compared SEPIC. The can reduce operation control method are described work. experimental results for 500 W prototype also discussed. Experimental show unlike SEPIC, improved power efficiency balanced capacitor voltages.
