Abstract: The research work presents hysteresis current controlled three-phase PWM converter. The switching control is applied on three-phase bi-directional switches, to attain sinusoidal input current at unity power factor and constant output voltage. The dc-link voltage is controlled by outer loop fuzzy controller and PI controller. The converter can be used for regeneration or bi-directional power flow. The converter is especially suitable for mid to low power application (i.e., 5-15 kW).The bi-directional switches operate at low frequency, crossover zero voltage (at turn-on) and conduct for 1/12th of line voltage cycle. The THD analysis of the controlled input phase current shows significant reduction in the THD as compared to the uncontrolled input phase current. The dc-link voltage follows the reference value.
