| Abstract: | Abstract：A novel method which can automatically adjust the freewheeling time of winding current for the large magnetic torquer is proposed. The problem of the high back emf (electromotive force) generated by the large magnetic torquer is solved definitely without adding power devices. Adopting the novel method, the size of the circuit board can be reduced significantly and the thermal design of the Drive Circuit becomes simple. And the requirement of frequently changing direction of magnetic torque with small amplitude is satisfied. |
