CURRENT VECTOR CONTROLLED DEADTIME FOR MULTILEVEL INVERTERS

摘要

The present invention relates to a multi-level inverter circuit and an operation method thereof. The first main switch adjusts the first main switch and the first neutral switch during the generation of the positive half period of the multi-level inverter circuit output so that the first main switch switches to control the connection between the output node and both nodes of the multi-level inverter circuit , The first neutral switch switches to control the connection of the neutral node to the output node. And detects the direction in which the alternating current output of the multi-level inverter circuit flows. Level inverter circuit is switched to the dead-time between the switching of the first neutral switch and the first main switch during the generation of the positive half-period of the output of the multi-level inverter circuit when detecting that the alternating current output of the multi- .
