| Abstract |
The article describes and analyses three control methods for UPS systems. The first method is the hysteresis control with a single measured value. The second method is the microprocessor based, constant frequency PWM with a dead-beat controller. The third one is method with the use of variable structure controler-sliding mode. There are made comparisons about all three control methods
with respect of harmonic spectrum of sinusoidal output voltage. Presented are the simulation and experimental results of a single phase UPS and a three phase UPS with DY transformer. |
