HIGH GAIN DC-DC CONVERTER WITH SWITCHED CAPACITOR FOR SOLAR PV APPLICATIONS

Abstract

In this thesis a new method for voltage boosting is implemented with high gain DC DC converter with switched capacitor. Comparing to the traditional DC-DC converter, this new circuit topology, voltage can be increase to extreme level, by using combining of two active components which are MOSFET and passive components like inductor and capacitor, by controlling the duty cycle ratio of each MOSFET separately, a high voltage value is reached at the output of the DC-DC converter by adding capacitor and inductor voltages. Therefore, it can reach this extreme voltage. Grid connection transformer can be eliminated by using this method, cost of PV plant will be lower.
