Analysis of Single-Tube Forward Circuit Under Closed-Loop Control

Power supply is an indispensable part of electrical equipment. Switching power supply and linear power supply are the most widely used power supplies at present. Switching power supply is widely used in small and medium-sized household appliances, industrial automation equipment, medical equipment, military and national defense, aerospace technology and other fields. This paper describes the working principle of the forward converter, deduces its working conditions under continuous output current, and establishes a single-tube forward simulation model under open loop and closed loop control based on MATLAB Simulink simulation platform, and gives the simulation results and analysis. The simulation results show that the theoretical analysis is correct and can be used for reference in the practical application of forward converter.
