ELECTRONIC POWER ASSEMBLY HAVING BALANCING OF A VOLTAGE NODE IN THE INTERMEDIATE CIRCUIT

摘要

The invention relates to an electronic power assembly, such as an inverter, which has an intermediate circuit having two or more capacitors connected in series. According to the invention, a voltage node is located between the capacitors. A switching power supply is connected in parallel to one of the capacitors of the intermediate circuit. The inverter further has a direct voltage actuator connected to the two capacitors and the voltage node, which direct voltage actuator induces energy equalization between the two capacitors.
