Производитель: "LAP Lambert Academic Publishing"

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.
