Abstract :
A new H-bridge cascaded multilevel inverter which can do regenerative action for motor drive is proposed. The proposed system adds a regenerative unit to the usual non-regenerative cascaded inverter, and the zero-sequence voltage is controlled to keep the regenerated power constant. In this case about 20% of capacitance of the rated motor power is enough for the proposed unit to decelerate motor as fast as the acceleration rate for the fun drive. In this paper some simulation and numerical analysis are shared to show its availability.
