摘要

提出了一种由脉宽调制整流器和全数字控制逆变器组成的不间断电源系统(UPS)。UPS的额定功率为单相10kva，输入200v，输出200v / 100v。UPS的电源开关器件为PWM整流器和逆变器中的绝缘栅双极晶体管(igbt)，开关频率为14.7 kHz。输入电流和输出电压的瞬时反馈控制使输入电流和输出电压呈正弦波。整流器和逆变器的控制电路实现了全数字化控制。

A fully digital controlled UPS using IGBT's

An uninterruptible power system (UPS) which consists of a pulse width modulation (PWM) rectifier and inverter with fully digital control is presented. The rating of the UPS is single phase 10 kVA of 200 V input and 200 V/100 V output. The power switching devices of the UPS are insulated gate bipolar transistors (IGBTs) in the PWM rectifier and inverter working at a switching frequency of 14.7 kHz. The instantaneous feedback control of input current and output voltage results in sinusoidal input current and output voltage. Full digital control is achieved in the control circuit of the rectifier and inverter.<>
