Abstract :
A new kind of variable frequency speed-governing experiment system which has the structure of two parallel inverters at the DC bus and the output of the inverter driving two series asynchronous motors at the same shaft is presented in this paper. The results of the experiment show this creative AC variable frequency speed-governing experiment system can realize the load relationship of direct electromagnetic torque between the motor group, get the continuous control process easily for the reaction load and potential energy load during four quadrant operation, achieve total availability of the regenerative energy at any kind of load
