Disclosed is a pressure balancing clamp for a press-pack insulated gate bipolar transistor (IGBT) module. The pressure balancing clamp for a press-pack IGBT module includes a bracket, where the bracket is provided with two longitudinally arranged pressure equalizing plates in a sliding way; the pressure equalizing plates are connected through pressure sensors; the upper and lower ends inside the bracket are respectively connected with the pressure equalizing plates through hydraulic devices and a displacement compensation device; opposite surfaces of the two pressure equalizing plates are respectively provided with heat dissipation and confluence devices. The pressure sensors are in one-to-one correspondence with the hydraulic devices and are electrically connected. The hydraulic devices adjust the pressure according to the readings of the pressure sensors in corresponding directions, so that the pressure of the press-pack IGBT module is balanced.
