Abstract :
This paper proposes the design of a three-phase AC power supply with the three-phase unbalanced load applied. An accessible AC neutral point is established to balance three phases to be completely uncoupled in the main circuit. The proposed control strategy has been implemented on a 400 Hz, 1 kW three-phase AC power supply. The test results show that it performs quite well with symmetric three-phase output voltage waveforms under the unbalanced load.
