| Abstract: | The paper investigates the design skills and principle of a large-magnetic-torquer drive circuit, adopting pulse width modulation and H-bridge. The drive circuit can output linear-current with analog input signal. According to the characteristics of the large-magnetic-torquer electric parameters, a simple electric model is established and a method for determining electric parameters is presented. Also methods for eliminating the remanence and remarks of the circuit application are proposed. This kind of cir... |
