An Improved Bidirectional Resonant Converter Fed Motor Drive
Abstract
This paper proposes a soft switching isolated bidirectional LLC converter fed induction motor drive with a new control scheme. All the switches in the proposed topology can achieve soft switching. Compared with traditional isolated bidirectional dc–dc converters such as dual active bridge converter, the reverse energy and turn-off loss are reduced dramatically, and the conversion efficiency can be much improved. With the proposed new control scheme, the power flow direction and output power of the proposed converter can be changed automatically and continuously, which is attractive for energy storage systems to balance the energy and to keep the dc-bus voltage constant. Proposed circuit is validated by the simulation results.
