用于LCL型并网逆变器的电容电压全反馈方案以抑制电网电压谐波引起的电流畸变

For the LCL-type grid-connected inverter, grid voltage full feedforward scheme is an effective method to improve the quality of the injected grid current. However, in the applications where a step-up transformer is adopted and its leakage inductance serves as the grid-side inductor, it is difficult to directly measure the grid voltage. For this case, the capacitor voltage full feedback scheme is p...
