Three Phase PWM Rectifiers-Design, Simulation Study (Paperback) (ISBN-13: 9783659185021)

Solid state power frequency changers are used for various purposes.The usual practice to get variable frequency power source is to use rectifier-inverter combination.Unfortunately the conventional diode/thyristor bridge rectifiers at the input side cause several problems such as: low input power factor, considerable harmonic distortion of ac currents and harmonic pollution on grid. The PWM rectifier is a preferred choice for providing ac to d.c conversion, due to its capability of input p.f regulation, line harmonic current mitigation, d.c voltage control and bidirectional power flow.In this thesis work, the theory behind a three phase PWM rectifier has been studied.a controller is designed to regulate the output voltage and input power factor.The entire system with its controller is modeled and simulated in MATLAB-simulink to verify the effectiveness of the proposed control strategy, to set the controller gains exactly to ascertain certain ratings of few hardware implementation.In this thesis work, real time simulation of a three phase PWM rectifier system with the proposed control strategy has been done using FPGA.
