摘要：This paper designs the switch adjustable constant current source based on the current mode PWM control chip UC3846, the power reach to 8kw, current 0 similar to 15A continuously adjustable. It uses the 12 control method to ensure the accuracy of the output current stability and improve the dynamic performance and response speed of the system. Feedback signals achieve in external circuit of the chip UC3846, they independent to each other to ensure the accuracy of the control signal. The model of UC3846 and the power supply were built by using Matlab Simulink separately. After building Close models, the circuit was simulated by using Simulink, and its simulation results reflected the output of power supply truthfully which played a good guide for the circuit design and experiment, to avoid detours and reduce risk.
