Abstract Flywheel energy storage system (FESS) is very important in the future for its high efficiency, energy saving and clean. Although there are some products in the market currently, the high-power FESS is still under investigation. A bidirectional DC-DC circuit applied in the high-power FESS was proposed in this paper, which used quasi-resonant zero voltage switching (QRZVS) technique and achieved the two-way flow of energy. The QRZVS had characteristics such as simplified structure and low switching loss, realized the ability of quick charge & discharge and reduced the electromagnetic interference (EMI) level of the system.
