| Abstract |
This paper presents a new range of medium voltage motor drives with a three-level neutral point clamped inverter using high-voltage IGBTs. Different line side converters are available, including a twelve pulse diode rectifier and an active front end converter in the same configuration as the inverter. Innovative features of the drive include series-connection of high-voltage IGBTs and a novel isolated voltage and current sensing system with fibre optic data transfer. The motor control is based on field-oriented vector control and an optimised PWM modulator, so that switching losses and current harmonics are minimised, resulting in no motor derating. A similar arrangement is used to control the active front end converter. The paper also includes information on the realisation of the converter and experimental results from laboratory and field tests. |
