Soft-Charging Effects on a High Gain DC-to-DC Step-up Converter with PSC Voltage Multipliers

Abstract

This paper proposes a split-phase control diagram for a new design of a DC-to-DC boost converter which is called PSC-boost and studies its performance. The PSC-boost has two sides, the primary is a PSC converter and the secondary is a DC-to-DC boost converter. The effect of applying the split-phase control diagram helps reduce the output impedance successfully and increases efficiency by 3%. The simulated and analytical results have been proven to validate the effect of the split-phase diagram. The simulated design contains five switches, five capacitors, seven diodes, and three inductors to step up 10V into 160V at 200KHz and 100KHz switching frequencies. The LTspice simulator was used to design and test the proposed model.
