摘要（英）：

The invention discloses a phased large current source generator device which is composed of three wireless phased current sources. Each wireless phased current source includes an AC/DC isolation powermodule, a DC/AC inverter module, a DSP master controller module and an ARM principal computer module. Each AC/DC isolation power module is configured to convert single-phase 220V power, three-phase four-wire power and three-phase five-wire power into low-voltage DC power through rectification and isolation. Each DC/AC inverter module is configured to convert low-voltage DC power into a low-voltage AC large current source. Each DSP master controller module is configured to make a driving signal communicate with the corresponding ARM principal computer module. Each ARM principal computer moduleis configured to output a current instruction, recover an output current and control the current precision, frequency and phase. Each wireless phased current source includes a positive output pole and a negative output pole. The positive output poles of the wireless phased current sources are connected to one side of a load, and the negative output poles of the wireless phased current sources areconnected to one point. Power grid protection equipment can be better detected.
