介绍了一种带有 DE 类振荡器的新型谐振 DC/DC 转换器,及其分析和实验结果。它由一个 DE 类功率振荡器和一个 D 类变压器中心抽头整流器组成。 DE 类振荡器可确保开关上的低峰值电压,并且可以比传统振荡器更小,因为 DE 类振荡器不需要额外的电路来驱动 MOSFET。 D 类整流器具有较低的开关损耗和噪声。在 2 MHz 和 2.5 W 下测得的效率超过 80%。
A new resonant DC/DC converter with Class DE oscillator is introduced, along with its analysis and experimental results. It consists of a Class DE power oscillator and a Class D transformer center-tapped rectifier. The Class DE oscillator ensures a low peak voltage across switches and can be smaller than a conventional one because the Class DE oscillator does not need an additional circuit to drive MOSFETs. The Class D rectifier offers low switching losses and noise. The measured efficiency was over 80% at 2 MHz and 2.5 W.
