Abstract :
With introduction of recent standards on limiting harmonic pollution of electrical power distribution system, three-phase PWM converters are being considered as prime candidates for interfacing high-power electronic equipment to power supply lines. In these applications, converters can provide input currents without distortion and with unity power factor. In this paper, a unified discrete event model is given for power electronic circuits based on a hybrid system theory. Based on this model, FPGA switching control strategy for a three phase converter is developed. The functionality of a three phase converter is discussed from a discrete-event point of view. Recently developed hybrid based approach for modeling of discrete event systems is applied for modeling, simulations and implementation of a power factor control, protection and steering functionality three-phase converter. A DSP / FPGA based digital control platform for converter system, built in the laboratory, is presented and discussed.
