It also deals with comparison of the four different switching control modes: phase-mode control, sinusoidal PWM mode control, pulsedepletion mode control and packet-mode control. Numerical harmonic analysis for total harmonic distortion is used. Simulation and preliminary results of experimental verification are given in the paper.
