摘要：

Inverters in electrical drive systems are commonly built up as a three-phase two-level voltage source topology, leading to an output current ripple inversely proportional to the switching frequency. To reduce this ripple without increasing the switching frequency of the power transistors, this paper presents a control method for an inverter topology with inverter branches, each consisting of several individual legs. They are pulsed in an interleaved manner and the outputs are connected via inductors. To avoid circulating currents, the control strategy uses a decoupling network connected downstream to controllers for the individual currents. This results in improved control behaviour.
