Abstract：A new type of magnetically integrated high gain coupled inductor voltage multiplier boost converter is proposed. The converter is composed of two boost topologies with coupled inductors. The two switches work in the same way. The voltage gain of the converter is increased by changing the turns ratio of the two coupled inductors. The equivalent inductance of the coupling inductor in different modes and its influence on the working state of the converter are analyzed. The main working waveforms and the equivalent circuit diagrams of each mode of the converter are given. The expression of the voltage gain of the converter is derived. The voltage and current stress of the switch and diode are analyzed. In order to reduce the current ripple of the inductor, the magnetic integration of the two coupling inductor units is carried out and the magnetic set is given The expression of the current ripple of the formed inductor. The leakage inductance model of coupled inductor is established and the expression of the influence of leakage inductance on the voltage gain of converter is derived. The analysis results show that the converter has the advantages of high voltage gain, low voltage stress and small current ripple. The correctness of the theoretical analysis is verified by experiments.
