Induction motor inverter system, has inverter driving induction motor by converting DC link voltage into AC voltage of variable frequency and variable voltage relative to voltage pulse signal output from controller

摘要

The system has a controller (30) determining various modes relative to a detected DC link voltage and a preset elapsed time. The controller outputs a voltage pulse signal relative to a selected mode. An inverter (11) drives an induction motor (IM) by converting the DC link voltage into an AC voltage of variable frequency and variable voltage relative to the voltage pulse signal outputted from the controller.
