Abstract

In this article, a new boost converter with zero-voltage switching capability has been introduced. In this structure, only by adding an auxiliary inductor to the conventional boost converter and splitting the output capacitor, the desired soft-switching condition is provided. The main advantages of this structure are its simplicity and ZVS performance of the semiconductors. The ZVS turn-on of the switch has been achieved within the DCM operation of the applied auxiliary inductor. Meanwhile, the ZVS turn-off of the power switch is obtained by charging process of the switch's parallel capacitor. In addition, the power diode turns off with zero-current switching condition. In this paper, the voltage gain, voltage stress across the semiconductors, and the efficiency analysis of the converter have been investigated in the steady state analysis. Also, the comparison results of this structure and other similar topologies have been mentioned. Finally, a simulation of this structure has been implemented in PSCAD/EMTDC software, and the simulation waveforms of the semiconductors have been obtained and comprehensively illustrated to prove the theoretical calculations.
