用于快速响应Buck变换器的自励磁平衡式无源可变电感

To improve the transient response speed of single-phase voltage regulators (VRs), this article proposes a self-excitation, balanced, passive variable inductor for a fast-response buck converter. The dc bias component of the buck converter's inductor current intensifies with increasing load, acting as an excitation source that induces magnetic core saturation, achieving inductance reduction. This m...
