Abstract

Abstract: Aiming at the lack of the theory and test methods for the transient characteristics of DC (direct-current) transformers and the difficulty of the existing test power supply to meet the test requirements, the step response characteristics of the transformers are studied by designing the step voltage source system of the DC voltage transformers. Capacitor energy storage technology design capacitor energy storage square wave power supply. At the same time, the control loop uses voltage feedback to improve the output voltage stability. The simulation results show that the top of the waveform of the step voltage source system is very flat, there is no obvious overshoot at the leading edge of the output voltage waveform, the stabilization time is much less than 100 μs, and the leading edge rise time is less than 10 μs, which meets the system requirements.
