摘要

该不间断电源(UPS)由高输入功率因数整流器、DC/DC功率变换器和脉宽调制(PWM)逆变器组成。而在逆变电路中，由于设计了分路扼流圈缓冲器，可以在不给开关元件驱动脉冲死区的情况下避免短路故障。此外，由于设计了LD缓冲器，电流浪涌和电压浪涌不会发生。通过实验验证了开关式缓冲器的性能、LD缓冲器和分路扼流圈缓冲器的有效性。本文还报道了这些方案的实验结果。

A novel high efficiency UPS using improved inverter and DC to DC converter

The uninterruptible power supply (UPS) presented combines a rectifier of high input power factor, a DC/DC power converter and a pulsewidth-modulated (PWM) inverter. However, in the inverter circuit, because a divided choke snubber was devised, short circuit failure can be avoided without giving the drive pulse of switching element a dead time period. Also because an LD snubber was designed, the current surge and the voltage surge do not occur. The performance of the switched snubber, the effectiveness of the LD snubber and of the divided choke snubber were verified by the experiments. Experimental results of testing these schemes are reported.<>
