Abstract

A zeta converter eliminates many of the limitations in the previous version of DC-DC converters like sepic, buck and buck-boost converters. But due to its open loop operation there is discontinuity in the output current whenever there is variation in the load. Due to this discontinuous conduction, power factor is affected at the input supply and hence high RMS values of the currents causes high levels of stress in the semiconductors. Our proposed work increases the power factor near to unity using novel control algorithm. Novel control algorithm(NCA) is a technique in which power factor is corrected using parameters available at the input and the output side of the converter. This technique does not require any separate circuit for power factor correction and it is implemented using a microcontroller.
