I. Introduction
Power DC-DC converters (step up step down) are gaining ever-increasing importance due to its enormous advantages. The interest on a compatible power DC-DC converter is increasing recently for obtaining desired power conversion in different fields like renewable energy, high and medium power applications etc [1]. High power conversion is greatly essential to meet the system demand in many applications. Boost converter is one kind of step up DC-DC converter which provides higher output dc voltage from low input voltage [3]. But there are some disadvantages such as it gives large voltage and current ripples, reverse recovery problem, large voltage stress on semiconductor devices etc. These reduce the stability and efficiency of the system [7, 11]. To solve these problems many kind of techniques are studied in various fields of research arena. Among them, interleaving or multi-phasing methods are notable solution to solve the problems.
