Beschreibung
Zusammenfassung:	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.
