Abstract
The utility model discloses a coupled inductor realizing high-gain double voltage boost converter, comprising two switch transistors, two clamping diodes, two free wheeling diodes, an output diode, a clamping capacitor, a double voltage capacitor, an output capacitor and two coupled inductors with two different windings respectively. Two coupled inductors make the high-gain of the converter improved and lower the voltage pressures of the switch transistors and the diodes. Zero-current switching-on of the switch transistors and soft turn-off of the diodes are realized by means of the coupled inductor leakage inductance which is absorbed by a clamp circuit composed of the clamping diodes and the clamping capacitor to achieve the switch transistor turn-off voltage spike and a lossless transfer of the power. The double voltage circuit further improves the high-gain of the converter and lowers the voltage pressures of the switch transistors and the output diode. The input current ripple is controlled and lowered by interleaving and transformer paralleling.
