An aging test system of motor controllers based on the PWM rectifier

A new aging test system of motor controllers based on the PWM rectifier is introduced. The new system contains no electrical machines and two motor controllers can be tested at the same time. Compared with the traditional aging test system, the new system has less operating loss and takes less space. The results of the simulations and the experiments demonstrate that the new system can work stably, save more energy and have good practical value.
