Abstract
This paper presents a control scheme for a single-phase AC-to-DC
power converter with three-level pulsewidth modulation. A single-phase
power-factor-correction circuit is proposed to improve the power
quality. The hysteresis current control technique for a diode bridge,
with two power switches is adopted to achieve a high power factor and
low harmonic distortion. A control scheme is presented where the line
current is driven to follow the reference sinusoidal current which is
derived from the DC-link voltage regulator, the capacitor voltage
balance compensator and the output power estimator. The blocking voltage
of each power device is clamped to half of the DC-link voltage. The high
power factor and low current total harmonic distortion are verified by
computer simulations and hardware tests
