摘　　要：目前,单相UPS的逆变电路主要采用半桥结构。但普通全桥型PFC电路难以为其提供电源,而双半波PFC电路适合为半桥逆变电路提供电源。针对单相UPS的一种双半波PFC电路,分别使用UCC28180D和TMS320F28027作为控制芯片,进行了控制系统设计。结果表明,TMS320F28027更适合双半波PFC控制系统的设计,为半桥逆变电路的前级PFC设计提供了一种思路。At present, the half-bridge inverter circuit is used in single-phase UPS. It is difficult to provide appropriate power supply for the half-bridge inverter using ordinary full-bridge PFC, but dual half-wave PFC could do it easily. The control system respectively based on UCC28180 D and TMS320F28027 was designed for a dual half-wave PFC in single-phase UPS. The results show that TMS320F28027 is more suitable for dual half-wave PFC control system design. And this paper could help designing of PFC for the half-bridge inverter.
