利用感性终端特性增强双频带电网模拟器的功率分配

The grid-interaction stability of the converter may vary with grid impedance conditions, and needs to be validated before field deployment. To facilitate stability tests toward grid-connected converters, a dual-frequency-band grid emulator has been proposed, which consists of an impedance-forming converter (IFC) switching at high frequency, and a power-supporting converter (PSC) switching at low f...
