In this paper, a current-limiting scheme is proposed for the voltage-controlled inverter. The method utilizes instantaneous current to quickly activate a resistive fault-current-limiting virtual impedance ( $R_{\mathbf {FCL}}$ ) to suppress the instantaneous impulse current and steady-state overload current, which can be directly integrated into the existing voltage-type control scheme. When a fault occurs, the inverter can be kept in the voltage control mode without mode switching. After the fault is cleared, it can automatically return to the...
