| Abstract |
One main aspect in the development of Uninterruptible Power Supply Inverters (UPS) is the reduction of the losses. This paper shows the effects of reducing the losses by hard and soft switched IGBT Inverters with three different DC-link voltage levels. All inverters are PWM controlled for sinusoidal output voltage. The efficiency of the inverters is measured. A possibility for determining the losses in each semiconductor in the powerparts is presented. The efficiency-curves will be presented and the losses are divided up in switching and forward power losses. |
