Abstract: The implementation of a constant frequency PWM scheme for shaping the input current waveform in a single phase ac-dc boost converter is presented in the paper. The method controls the switching devices of the converter in such a way that the average of input current over a switching interval tracks the average of the sinusoidal reference current over the same interval. Simulation studies showed that the method gives satisfactory operation for different loads and variable power factors. Practical implementation of the control method was done on an IGBT converter switching at 10 kHz using a 80386 processor based system. Issues in the practical implementation of the method are addressed in this paper. The experimental results showed that the proposed method is capable of stable, transient-free operation at various conditions, loads and power factors. The excellent dynamic response of the system with the proposed control is also illustrated with experimental results.
