Modeling Analysis of Current and Voltage Double Closed Loop Control Buck PWM Power Supply System
Summary:
PWM switching power supply systems generally use current and voltage double closed loop control. Based on the power stage model of PWM step-down switching power supply, the system transfer function block diagram of the step-down PWM switching power supply based on average current control is obtained, and the current loop gain is analyzed by Matlab.
