In order to solve the problems of insufficient boost capability and large input current ripple of traditional Boost circuit, a novel DC/DC converter based on coupled inductance is proposed. The zero input current ripple is achieved by combining coupling inductance and capacitance in the front stage of the converter, and voltage gain of the converter is expanded by using coupled inductance voltage doubling unit in the back stage of the converter. A clamping circuit with diode and capacitor is introduced to suppress the voltage spike caused by leakage inductance, thus forming a new converter topology. Based on the circuit theory, the working principle and working characteristics of the converter are analyzed, and by taking the DC boost stage in the photovoltaic power generation system as the application background, experimental verification and analysis are carried out on the Simulink simulation platform. The results show that the converter has the characteristics of the high voltage gain, zero input ripple and low voltage stress. [ABSTRACT FROM AUTHOR] |
