SYSTEM AND METHOD FOR POWER CONVERSION OF LC FILTER WITH ADDITIVE CAPACITOR

A system and method for a high efficiency power converter incorporating a half-bridge topology with one or more additional upper capacitors and drain-source capacitors. The converter includes a DC voltage terminal and a DC link capacitor coupled across positive and negative DC terminals of the DC voltage terminal. The converter further includes a pair of power switching elements including a high side switch and a low side switch coupled together at a midpoint node. The converter further includes an LC filter having a switch-side inductor, a lower capacitance coupled between a second end of the switch-side inductor and the negative DC terminal; and an upper capacitor coupled between the second end of the switch-side inductor and the positive DC terminal. The converter may further include a drain-source capacitor coupled across the drain and source terminals of the switch. 一种用于高效率功率转换器的系统和方法，该功率转换器结合具有一个或多个附加的上电容器和漏-源电容器的半桥拓扑。该转换器包括DC电压端子和跨越DC电压端子的正和负DC端子耦合的DC链路电容器。该转换器进一步包括功率切换元件对，该功率切换元件对包括在中点节点处耦合在一起的高侧开关和低侧
