Abstract :
A PWM control method for a switch-mode rectifier (SMR) based on the idea of coordinate transformation is presented. This method realizes sinusoidal input current waveforms, a controllable input displacement factor, and an arbitrary output voltage waveform. This method is advantageous for reducing higher and fractional harmonic components of the input waveforms and is suitable for real-time control. Simulations and experiments are carried out to confirm the feasibility of the proposed method
