一种适用于宽输入电压范围的高效非隔离恒流LCC谐振变换器

In this article, we propose a simple structure highly efficient low-element-count nonisolated constant output current resonant converter for wide input voltage range and high-efficient applications. The converter is developed by combining a basic buck–boost converter with a half-bridge LCC resonant converter to improve the adjustable voltage conversion ratio. In the proposed structure, most of the...
