High Gain Ultra Boost Converter With Voltage Regulation

Nowadays high gain boost converters are efficient for many applications. This work introduces a high gain ultra boost converter with voltage regulation by increasing voltage gain and reducing voltage stress across the switch. This converter uses an autotransformer with coupled inductor integrating on the same core to achieve high output voltage about ten times of input voltage without using endmost duty cycle. And also a Switched/Diode voltage multiplier cell is using in coupled magnetic circuit to recycle the leakage energy. Methods used here for voltage regulations are Line regulation and Reference regulation. The simulation of proposed converter is verified using MATLAB/SIMULINK software. Modes of operation and analysis of the converter are also discussed.
