Power electronics for internal combustion engine driven mobile working machine e.g. truck, has inverter that is connected with voltage converter as secondary inverter, so that voltage converter is operated as energy storage device

摘要

The power electronics has inverter (19) through which three-phase current of direct current (DC) voltage intermediate circuit (21) is inverted in three-phase in both directions, so that the inverter connected to three-phase motor can also be operated as a generator. The inverter is connected with DC-DC voltage converter (23) as secondary inverter (24), so that the voltage converter is operated as an electrical energy storage device. The inverters are integrated in a common housing (12).
