摘要
This paper proposed a novel high step-up converter with double boost paths. The circuit uses two switches and one double-path voltage multiplier cell to own the double boost and interleaved effects simultaneously. The voltage gain ratio of the proposed DC-DC converter can be three times the ratio of the conventional boost converter such that the voltage stress of the switch can be lower. The high step-up performance is in accordance with only one double-path voltage multiplier cell. Therefore, the number of diodes and capacitors in the proposed converter can be reduced. Furthermore, the interleaved property of the proposed circuit can reduce the losses in the rectifier diode and capacitor. The prototype circuit with 24-V input voltage, 250-V output voltage, and 150-W output power is experimentally realized to verify the validity and effectiveness of the proposed converter.
