| 摘 要： | 为了进一步提高UPS(Uninterrupted Power Supply)输出的动态和稳态性能，介绍了一种采用电流环做内环的双环控制技术，实现了对负载电流扰动的解耦。同时为了补偿输入电压的不稳定，采用输入电压前馈控制。文中就提到的控制方法分别进行了时域和频域仿真分析，并以DSP(TMS320LF2407)为控制芯片进行了实验验证，结果显示逆变器输出电压在恶劣的负载条件下波形畸变很小。

| Abstract: | A two-loop control technique with regulation of filter capacitor-current for LC filter is introduced, which can realize load disturbance decoupling and improve dynamic and static performance of UPS output. At the same time, in order to compensate for instability of VDC, input voltage forward feedback is adopted. Both the frequency-domain and time-domain behavior of the proposed control scheme have been examined in this paper. An inverter control system based on DSP(TMS320LF2407A) was constructed to verify the control law. The results show that the output voltage of the controlled PWM inverter has little distortion even under rough load conditions. |
