| Abstract: | The short circuit currents and electromagnetic torque of a hybrid AC/ DC power supply system are analyzed when sudden short circuits occur sim ultaneously at AC and DC sides,and their analytical expressions and calculation results are presented.The experim ental results of the analogue prototype of a machine show that the analytical expressions and calculation method are correct,thus can provide a theoretical basis for composite protection of such kind of power supply system s. |
