摘 要:通过对传统三相桥结构的双向逆变器在飞轮工作于充电、放电过程中绕组内的电流情况分析,提出了更适用于高速下、方波电机结构储能飞轮的新型双向逆变器拓扑。该双向逆变器采用独立的Buck、Boost电路来实现储能飞轮的充、放电控制。实验结果证实了采用独立的升、降压电路来分别实现充电及放电操作,极大的改善了绕组电流的波形,使高转速下飞轮能量的精确控制成为可能。 关键词:飞轮储能;Buck;Boost;高速;方波电机
Abstract: In this paper,analyzing current conditions within the windings in the charge and discharge process of the flywheel when the reversible transducer of the traditional three-phase bridge structure was -adopted,a new-type bidirectional inverter topology which is more suitable for energy storage flywheel of high-velocity,square-wave motor structure was proposed.Simulation results show the use of independent boost and buck circuits to respectively realize charge and discharge operations can greatly improve the winding current waveform,and make the precise control of the high-speed flywheel energy possible. Key Words: Flywheel energy storage;Buck;Boost;High-velocity;Square-wave motor
