The invention relates to a high boost converter based on coupling inductors, which overcomes the defect that the traditional Boost converter is difficult to realize high voltage conversion ratio and high conversion efficiency, the coupling inductors are added in a converter circuit, and the high boost converter can be realized by adjusting the turn ratio between the primary winding of the first coupling inductor and each secondary winding. A high voltage conversion ratio and high voltage output are obtained; the boost function is realized by adjusting the duty ratio of the switch tube, and the switch tube is prevented from working under an extreme duty ratio condition; the voltage stress that the switch tube needs to bear is low, the performance requirements for components such as the switch tube are reduced, and the circuit can be better applied to a power system of a new energy charging pile.

    本申请涉及一种基于耦合电感的高升压变换器,克服了传统Boost变换器存在的难以实现高电压转换比和高转换效率的缺点,在变换器电路中加入了耦合电感,通过调整第一耦合电感的初级绕组和各个次级绕组之间的匝数比,获得高电压转换比以及高电压输出;通过调节开关管的占空比实现升压功能,避免开关管工作于在极端占空比条件;开关管需要承受的电压应力较低,降低对开关管等元器件的性能要求,能够更好的应用于新能源充电桩的电力系统中。
