Abstract :
Harmonic currents caused by power converters is serious problem in many electric power systems. Thyristor and diode converters are widely used in industrial applications these days and they can be considered as a typical example causing that electrical pollution. Nowadays, an increasingly popular trend is to compensate the harmonics by using six-switch active power filters. In this paper the capability of three-switch current-source PWM rectifier (3SW-CSR) to act as an active power filter and to compensate the harmonics caused by other converter is studied. It is shown by analysis, simulations and experimental tests that 3SW-CSR offers an effective and low-cost solution to improve the quality of electrical power in applications where group of three-phase rectifiers is used
