Abstract :
This paper describes a single phase static UPS (uninterruptible power supply system) comprising of an inverter which uses high current transistors for a power range which was reserved to thyristors up to now. A microprocessor controlled measuring system calculates all data of interest such as input and output power, efficiency etc. The basic theory of the PWM inverter and the microprocessor unit is handled in detail.
