A Soft-Switching Isolated Bidirectional Converter Fed Induction Motor Drive

Gundoji Pavan, Kumar Tech, K Suresh
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
