摘要： A UPS is adapted to receive power from a polyphase AC source. The UPS includes power conversion circuitry adapted to convert the power supplied by the polyphase AC source to DC power. The power conversion circuitry includes phase conductors. The UPS also includes a neutral coupled to an output of the UPS, a plurality of input capacitors coupling the phase conductors to the neutral, a DC system including a positive DC bus with a positive DC bus voltage and a negative DC bus with a negative DC bus voltage, and a control system. The control system is adapted to control a difference between a magnitude of the positive DC bus voltage and a magnitude of the negative DC bus voltage by controlling a DC voltage across the input capacitors.
摘要翻译： UPS适用于从多相交流电源接收电力。 UPS包括电源转换电路，其适于将由多相AC电源提供的电力转换为DC电力。功率转换电路包括相导体。 UPS还包括耦合到UPS的输出的中性点，将相导体耦合到空档的多个输入电容器，包括具有正DC总线电压的正DC总线和具有负DC的负DC总线的DC系统总线电压和控制系统。该控制系统适于通过控制输入电容器两端的直流电压来控制正直流母线电压的大小与负直流总线电压的大小之间的差异。
