摘要： A power converting apparatus and method providing for the addition of a fourth power connection wire to the neutral point of the normal three phase load circuit (105). This allows delivery of combined current from the center of the DC link voltage to load. The added control enables a third harmonic injection to flow and allows for increased power rating per peak amp handled by the conversion system. Limiting of faults to the positive half versus the negative half of the DC system allows for more robust behavior when encountering these fault conditions.

摘要翻译： 一种电力转换装置和方法，用于向正常三相负载电路（105）的中性点添加第四电力连接线。 这允许将组合的电流从DC链路电压的中心传递到负载。 添加的控制使得三次谐波注入流动，并允许由转换系统处理的每个峰值放大器的额定功率增加。 将故障限制在直流系统的正半部分与负半部分之间允许在遇到这些故障条件时具有更强大的行为。
