摘要：

根据双负载VIENNA型整流器拓扑结构,建立了基于端口受控的耗散哈密顿（PCHD）数学模型。提出了利用无源控制器控制交流电流,PI控制器控制直流电压的无源混合控制策略。基于PCHD数学模型,采用互联和阻尼配置方法设计了无源电流控制器,实现了交流电流快速跟踪期望值,并保证整流器的稳定性。Matlab/Simulink仿真结果表明,基于PCHD模型的无源混合控制策略能够使直流侧电压快速跟踪期望值,网侧电流正弦化及单位功率因数,并对负载变化具有良好的鲁棒性。

Abstract:

PCHD mathematical model was established according to the topology of double-load VIENNA-type rectifier. A passive hybrid-control strategy between passive controller for grid AC current and PI controller for DC voltage was presented. Based on PCHD mathematical model, the passive current-controller was designed with the method of interconnection and damping assignment, thus grid AC current can be fast to given value and ensure the stability of the rectifier. Simulation results show that passive hybrid-control strategy based on PCHD mathematical model not only make DC voltage to be a given value fast, but also can achieve sinusoidal grid AC current, the unity power factor and good robustness to load change.

Key words: VIENNA-type rectifier, PCHD, double-load, passive hybrid-control, neutral-point voltage balance
