A virtual synchronous generator (VSG) strategy can introduce the rotational inertia and damping characteristics of the synchronous generator to the static inverter, e.g., PV, wind generation, and ESS, which are used to enhance the system frequency su

The terminal-connected series dynamic braking resistor (SDBR) is applied to assist the low-voltage ride-through (LVRT) of the doubly-fed induction generator (DFIG). With the fault current and switch-in of the SDBR, the stator voltage oscillates, thus

To improve the DC-bus voltage and the switching frequency of the boost circuit and reduce the volume of the passive filter element and the heatsink, the SiC MOSFET should be used as the main switching device. It is necessary to keep the SiC MOSFET wo
