Low-voltage high-gain cubic Boost converter

The invention relates to a cubic Boost converter with low voltage pressure and high gain. Comprising a direct current power supply (Uin), a power switch tube (VT), a first diode (VD1), a second diode (VD2), a third diode (VD3), a fourth diode (VD4), a fifth diode (VD5), a sixth diode (VD6), a first capacitor (C1), a second capacitor (C2), a third capacitor (C3), a fourth capacitor (C4), an output capacitor (C5), a first inductor (L1), a second inductor (L2), a third inductor (L3), a fourth inductor (L4) and an output load. When the boost converter works, only one switching tube needs to be controlled, the complexity of a control circuit is reduced, in addition, compared with a traditional Boost converter, the boost converter has the high voltage gain, and meanwhile the switching voltage stress is obviously reduced. 本发明涉及一种低电压压力高增益三次型Boost变换器，包括直流电源（Uin）、功率开关管（VT）、第一二级管（VD1）、第二二极管（VD2）、第三二极管（VD3）、第四二极管（VD4）、第五二极管（VD5）、第六二极管（VD6）、第一电容（C1）、第二电容（C2）、第三电容（C3）、第四电容（C4）、输出电容（C5）、第一电感（L1）、第二电感（L2）、第三电感（L3）、第四电感（L4）和输
