Two reduced-switch-count ac/ac dc-link six-leg converters are investigated in this paper. The proposed topologies allow for three-phase-to-three-phase power conversion to supply a three-phase four-wire load without any capacitor dc-link-midpoint connection. The converters provide bidirectional power flow and power-factor control. Pulsewidth modulation techniques are derived by using the concept of local and general apportioning factors. The overall control strategy for providing dc-link voltage… CONTINUE READING
