With introduction of recent standards on limiting harmonic pollution of electrical power distribution system, three-phase PWM converters are being considered as prime candidates for interfacing high-power electronic equipment to power supply lines. In these applications, converters can provide input currents without distortion and with unity power factor. In this paper, a unified discrete event model...
A new duty cycle parallel control method for AC-DC converter with power factor correction is proposed. The duty cycle required to achieve unity power factor consists of two terms: current term and voltage term. They are calculated directly based on the reference current and sensed inductor current, input voltage and output voltage. It requires only one multiplication and three addition operations...
A single phase AC-DC converter with unity power factor (UPF) have been proposed in this paper. The hysteresis current control scheme is employed to track the line current command while the control signal of the four power switches are derived from the power balance calculator (PBC) for achieving a fast response, high power factor during steady state operation with a constant load. The proposed control...
