Bridge circuit is formed by fully controlled power electronic devices IGBT.
Current transformers are used for real-time current detection, and then information acquired is sent to the Digital Signal Processor (DSP) for analysis. Then the drive power circuit actuates the IGBT, so as to control the internal energy-storage capacitor to transfer and equally distribute 3-phase unbalanced current and to realize balance among the 3-phase currents.
Full protective function:
The device has a full range of protective functions such as over-voltage, overload, under-voltage, short-circuit, phase loss, zero sequence overrun and much more function.
