|Abstract:||A novel inductor voltage control (IVC) method capable of achieving any input power factor including unity is being proposed for buck-type ac-dc pulsewidth modulation (PWM) converters. In this method, the input inductor voltage is kept within a hysteresis band about a sinusoidal template, thus ensuring sinusoidal input current. This control is much less sensitive to parameter and control signal changes than the existing Delta modulation control (DMC). In this paper, the IVC method is applied to a single-phase buck-type converter. Useful design results based on steady-state analysis have been presented. Simulation and experimental results have been provided to verify the theoretical results. The companion paper extends the applicability of the IVC control method to three-phase converters also. The proposed IVC method has potential in applications requiring ac-dc rectifiers with over-current /short-circuit current limit.|
