Abstract :
Summary form only given as follows. This paper describes a static synchronous compensator using a thyristor PWM current source inverter. The proposed system consists of a 3-phase thyristor bridge with a commutation circuit, a DC reactor; and AC filter capacitors. The 3-phase thyristor bridge operates os a current source PWM inverter with assistance of commutation circuit. The system operation was verified in detail through computer simulations with EMTP, and experiments with a scaled hardware model. The proposed system has two advantages of low switching loss and easy expansion of operation voltage through series connection of thyristors
