Abstract

Abstract: According to the requirements of the equipment power supply scheme in the DC power system, analyzes and compares the characteristics of typical power supply topologies, chooses the dual-transistor forward topology, and sorts out the key device parameter design methods and selection calculations in detail according to the application requirements. Focusing on the control loop analysis and modeling for power supply stability, a small-signal simulation model of the control system is built, and the control loop parameter design and stability are analyzed through simulation analysis. And a 200 W power level prototype is developed. The performance indicators of the prototype meet the design requirements, the control performance is stable, demonstrating the correctness and effectiveness of the theoretical analysis.

Key words: DC, Two-transistor forward, Switch power supply, Control loop
