A high-gain boost converter with voltage clamping based on coupled inductors

Abstract

The application relates to the technical field of power electronic DC converters, in particular to a high-gain Boost converter with voltage clamping based on coupled inductors, which comprises a DC voltage source, two coupled inductors with a transformation ratio of 1:n, seven capacitors, seven diodes and two mosfet switch tubes. ds The application solves the problem that the coupled inductor reversely and sharply increases the leakage inductance voltage at the moment when the mosfet switch tube is closed, and the mosfet switch tube V The application uses two main circuits to stagger and run, so that the input current is continuous and the input current ripple is small, the circuit continuously provides relatively stable energy, the voltage multiplication unit is adopted, the amplification multiple of the circuit is increased, even in the case that the voltage multiplication multiple is relatively large, the current ripple can be kept small. The application has the advantages of high voltage multiplication ratio, low device stress, high efficiency, easy control implementation, low cost, high cost performance and the like.
