High Efficiency High Voltage Gain Boost Converter using Zero Crossing Switching Multi-stage Voltage-Lift Cells


ไทย :

 A non-isolated high efficiency, high voltage step-up gain boost converter is proposed in this paper. A series of multi-stage voltage-lift cells with simple diode-capacitor-inductor configuration is used to provide very high voltage gain for the conventional boost converter. A passive snubber is connected in parallel with a switch in the boost circuit to provide zero-current turn-on and zero-voltage turn-off and thus achieve low switching losses. Analysis, design and implementation of the proposed circuit are explained and examined by both simulation and experimental prototype. The test results verified the feasibility of the proposed converter with switching frequency of 50 kHz and rated power of 400 W. The proposed converter achieved 96.0% of maximum efficiency and very high voltage gain of 12 for a series of 3 stage voltage-lift cells.
