| Abstract |
An integrated three phase variable frequency, voltage fed inverter and induction motor drive combination is presented. Rather than adding series inductance in each inverter leg in order to control simultaneous conduction fault currents, part of the induction motors leakage inductance performs the fault control function. Performance associated with a 4 kW 2 pole squirrel cage induction motor illustrates protection and derating aspects. Generally, motor output power is traded off against the level of fault protection desired. The protection afforded becomes more effective with increased motor voltage and power rating. |
