A Novel High Voltage Gain Quasi-Resonant Step-up DC/DC Converter with Soft-Switching
This paper presents a novel single-switch, high step-up DC/DC converter. The proposed converter operates in quasi-resonant (QR) mode, which presents many advantages. There are soft-switching conditions in the operation of this converter due to the leakage inductance (Lk) of the Coupled Inductor (CL). The power switch turns on under zero-voltage-switching (ZVS) condition. Besides, the diodes currents are zero during their switching process (ZCS). These features significantly reduce switching losses and increase the converter’s efficiency. In addition, the voltage gain of this converter is high due to the presence of CL in its structure. The operating principles and steady-state operation are discussed in each time interval. In order to verify the theoretical discussion, computer simulation is performed in Cadence/OrCAD software. The simulation results indicate validity of the converter specifications well.
