A New Burn-In Test System of Motor Controllers Using Zero-Sequence Current Control

摘要

A new burn-in test system of motor controller using zero-sequence current control is presented. The new system consists of two motor controllers and a three-phase reactor. The zero-sequence current control ensures that the three-phase current is symmetrical and sinusoidal, so that two motor controller can be tested at the same time. The results of the simulation demonstrates that the zero-sequence current control is able to ensure that the three-phase current is symmetrical and sinusoidal and can meet all the requirements of the burn-in test system of motor controller. The system uses less hardware, has less loss and it is more energy-efficient, more convenient.
