Research on Bi-directional Quasi-resonant Zero Voltage Switching DC-DC Converter for Flywheel Energy Storage System |
| |
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. |
