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… (More)
