首次提出了Boost型高频环节AC-AC变换器电路结构与拓扑族,它是由储能电感、输入周波变换器、高频变压器、输出周波变换器以及输入、输出滤波器构成.深入分柝研究了这类变换器的稳态原理特性与移相控制策略,提出并有效地解决了变换器的若干关键问题.以全桥桥式电路拓扑为例,进行了这类变换器的仿真和原理试验.研究结果表明,这类变换器具有高频电气隔离、电路拓扑简洁、两级功率变换(LFAC-HFAC-LFAC)、双向功率流、变换效率高、网侧功率因数高、负载适应能力强、负载短路时可靠性高等优点,为优良性能的正弦交流稳压器、调压器、电力电子变压器和同频波形变换器奠定了关键技术基础.

飞轮储能系统容错运行的研究

本文分析了飞轮储能系统易发生的四种电气故障,提出了改进的各相电流独立控制的容错拓扑.对比传统的电机中性点与逆变器直流端中点相连的容错拓扑,改进的拓扑在发生驱动电机绕组开路故障或逆变器器件单管发生开路、短路故障的情况下,系统仍能持续稳定地运行.本文对提出的容错拓扑及控制策略做了详细分析并给出仿真结果.
