A Zero-Transient Dual-Frequency Control for Class-E Resonant DC–DC Converters

In this article, a dual-frequency control method for regulating the output power in class-E resonant dc–dc converters has been introduced. As standard on – xmlns:xlink="http://www.w3.org/1999/xlink">off or other recently proposed controls, approach is based on ability of converter to alternately operate high- and low-power state. The solution twofold advantage: one hand, soft-switching capabilities (i.e., zero-voltage zero-voltage-derivative switching) are preserved both operating states; it possible reduce zero transient time required switch from state one. most straightforward consequence possibility increase very large values frequency at which two states switched, up same order magnitude as main switching converter. way, additional ripple introduced by can be decreased negligible value. validated measurements prototype between 4 8 MHz 500 kHz.
