Abstract: This paper presents a detailed comparative study between two different soft switching techniques used in PV applications. An extended range ZVS active clamped current fed full-bridge isolated boost converter has been studied and the comparison has been done with a soft switching boost converter using an auxiliary resonant circuit. The former uses the energy stored in the leakage inductance of the transformer and its magnetizing inductance to perform the soft switching whereas the latter uses a resonant circuit in order to carry out the same. A typical 500 W converter is employed to investigate both the converters. Comparisons have been made on the basis of operating modes and range of operation. Detailed operation, analysis and simulation results for the designs have been presented. The systems are modeled and simulated in PSIM 64 bit version 9.0 Environment.
