Description
Summary:This paper proposes a soft switching technique in a novel two stage buck-boost converter comprising from two identical separate units. The converter units are connected to each other by an interleaved inductor. The soft switching method utilized is Zero Voltage Transition which means turning on the switches while the voltage applied on them is equal to zero. This operation is done with establishing the gate pulses of the converter switches at the accurate time intervals. The soft switching operation of the converters has significantly effect in reducing the switching losses of the circuit, and causes an effective increment in the converter efficiency. This paper describes the procedure of the circuit operation to obtain the correct performance of the proposed converter. The simulation results have been done in the PSPICE software and depicted the accuracy of performing the ZVT method.
