The invention discloses a three-phase current imbalance management controller, a three-phase current imbalance management device and a control method. The three-phase current imbalance management controller comprises a DSP, a UI sampling module, and an IGBT driving module; the DSP is connected with the UI sampling module and the IGBT driving module; the UI sampling module collects set voltage andcurrent signals and sends the set voltage and current signals to the DSP; the DSP generates PWM waves that control an IGBT according to the received voltage and current signals, wherein the PWM wavesare sent to the IGBT driving module so as to be subjected to power amplification to drive the corresponding IGBT. According to the three-phase current imbalance management controller of the invention,three-phase current on a bus-bar is automatically sampled and detected, so that three-phase imbalance can be quickly detected out, and can be adjusted continuously, smoothly and quickly; and therefore, a three-phase current im
