Abstract

The closed-loop control circuit of full-bridge DC/DC converter for wind power generation is designed in this article. First of all, the small-signal model of full-bridge DC/DC converter is established, and then with the help of automatic control theory and Matlab software, the control parameters are set to derive the mathematic model of high-power full-bridge DC/DC converters with closed-loop control. In the end, the whole system is simulated with Pspice software, and the results showed that the whole simulation model of design according to the small-signal voltage scheme is feasible and double closed-loop control technology can obviously improve the dynamic characteristics and the stability of the system.
