A controller controls a balancer circuit, and is configured to: determine a difference value between a first DC link voltage value across a first DC link of a power converter and a second DC link voltage value across a second DC link of the power converter; determine a phase-angle and a magnitude of the difference value for an integer harmonic of a predetermined grid frequency; and provide a switching signal for switching between the first DC link and the second DC link based on the phase-angle and the magnitude. The controller is also configured to control a mid-point current at a mid-point terminal of the power converter in terms of magnitude and direction based on the switching signal.

Controller for controlling a balancer circuit

A power switch module includes a semiconductor die and a conductive busbar. The semiconductor die is electrically conductively mounted to the busbar. The module also includes a dielectric coolant fluid and the busbar and the semiconductor die mounted thereto are immersed in the dielectric coolant fluid. The module can be include in a power converter assembly.
