摘　　要：为了解决逆变器双环控制在抗负载扰动能力以及逆变器输出电压波形质量方面问题,建立了单相全桥逆变器模型,提出了在原有逆变器双环控制基础上引入负载电流前馈设置控制策略,并借助MATLAB进行了仿真分析。仿真结果表明,在引入负载电流前馈的设置后,该控制系统的稳定性有了显著提高,有效地改善了抗负载的扰动能力和逆变器输出波形质量。In order to the problems in anti - disturbance performance and inverter output voltage waveform quality for dual - loop control, this paper establishes the model of single - phase full - bridge - tied inverter, proposes the control strategy with load current feedforward setting on the basis of the original inverter dual - loop control, and simulates the strategy by MATLAB. The simulation result shows that the stability of the control system enhances ap- parently after bringing in load current feedforward setting, which improves anti - disturbance performance and in- verter output voltage waveform quality.
