Abstract	This work is to implement and simulate the DC excitation control of a wind induction synchronous generator (WISG) under autonomous generation mode using a micro-controller with reduced instruction set chip (RISC). The proposed DC excitation control is obtained from the generated AC voltage of the studied WISG through a step-down transformer, a rectifier, and a DC-to-DC buck converter to modulate the desired DC voltage of the rotor winding. Due to high-speed modulation capability of the proposed micro-controller, the voltage variation of the studied autonomous WISG under loading conditions can be effectively compensated. The studied WISG system is practically implemented in a laboratory 300 W wound-rotor induction machine driven by a DC motor. From the analyzed results, it can be concluded that the proposed WISG controlled by the RISC can provide good voltage profile under various loading and switching conditions.
