Method for controlling a converter unit for an electric machine of a vehicle, drive assembly for a vehicle, and vehicle

A converter unit for an electric machine of a vehicle, the converter unit comprising:

• an electric power source interface connectable to an electric power source,
• an electric machine interface connectable to an electric machine,
• at least one H-bridge, wherein a switch is provided on each leg of the H-bridge,
• at least one snubber capacitor, and
• a data processing apparatus comprising a memory storing instructions executed by a processor to:
• cause closure of a pair of switches for supplying electric current to the electric machine interface during a first predefined time span, and
• cause closure of the pair of switches for supplying an electric induction current to the electric machine interface during a second predefined time span and after a predefined waiting time,
• wherein the first predefined time span and the second predefined time span are associated with the same electric current supply half cycle,
• wherein the H-bridge and the at least one snubber capacitor are electrically interposed between the electric power source interface and the electric machine interface, and
• wherein the data processing apparatus is communicatively connected to the switches of the H-bridge.
