Abstract:
The present disclosure relates to a power converter configured for limiting switching overvoltage. The power converter comprises a pair of commutation cells. Each commutation cell includes a power electronic switch and a gate driver connected to a gate of the power electronic switch. A reference of the gate driver of a first commutation cell is connected to a ground of the power converter while a reference of the gate driver of a second commutation cell is connected to a collector of the power electronic switch of the first commutation cell. The gate driver of the second commutation cell has no negative voltage power input, either through using a single voltage power supply or by connecting a negative voltage connection of the dual voltage power supply to ground.
