Linear–Nonlinear Optimal Step Control for 1-kV SiC LLC Converters With Pulse Loads

语言:

中文摘要

针对脉冲负载需求,本文提出了一种线性-非线性步进负载控制策略。该方法通过计算初始开关频率和占空比,使变换器在从空载到满载的瞬态过程中,以最小的输出电压跌落和最短的调节时间达到满载稳态运行点。

English Abstract

The linear–nonlinear step load control is proposed to meet the requirements of the pulse load. The nonlinear optimal step control from absolute no-load to full-load is able to force the converter to reach the full-load steady-state operation point with the minimum output voltage drop and minimum settling time. The key is to calculate the initial switching frequency and the duty cycle of the first ...
