A circuit for minimizing energy provided to a ground fault includes a source, a multiple switches, an output filter, and a controller. The switches include a first side pair of switches and a second side pair of switches configured to provide an output signal based on the source. The output filter includes one or more energy storage elements coupled to the first side pair of switches or the secondside pair of switches. The controller is configured to receive a ground fault signal that indicates a fault has occurred and configured to generate a switch signal for the switches for a minimum energy state of the output filter and in response to the ground fault signal. 一种用于使提供给接地故障的能量最小化的电路，其包括源、多个开关、输出滤波器和控制器。开关包括被配置为基于源来提供输出信号的第一侧开关对和第二侧开关对。输出滤波器包括耦接至第一侧开关对或第二侧开关对的一个或更多个能量存储元件。控制器被配置为接收指示已经发生故障的接地故障信号，并且控制器被配置为针对输出滤波器的最小能量状态并且响应于接地故障信号来生成用于开关的开关信号。
