提出了一种基于压电谐振器(PR)的新型DC-DC转换器拓扑结构。介绍了其原理转换和稳态运行时的分析模型。制作了一台样机进行实验验证，初步验证了该转换原理。该样机最初工作在径向模式，在120~48V的输入输出电压下，功率转换效率高达10W，效率高于95%，16W时的转换效率为93%。此外，通过3-PR并行化，在输出功率为38W时，效率达到85%。厚度工作模式为1 MHz，当输入输出电压为120~48V时，输出功率为40W，效率为85%；当输入输出电压为200~60V时，输出功率为100W，效率为83.5%。这些初步结果表明，基于PR的DC-DC转换器具有良好的高低压转换和低功率转换性能。
This paper presents a new topology of DC-DC converter based on a piezoelectric resonator (PR). We introduce the principle conversion and an analytical model in steady state operating. A prototype was fabricated for experimental validation, and the first results demonstrate the conversion principle. The proposed prototype, operating initially in radial mode, achieved an efficiency higher than 95% for power conversion up to 10 W at 120 – 48 V input-output voltage, and an efficiency of 93% was measured for 16 W. Furthermore, an efficiency of 85 % at output power of 38 W was achieved by parallelizing 3-PRs. In addition, the thickness operating mode is demonstrated at 1 MHz, and exhibited an output power of 40 W with an efficiency of 85 % for 120 – 48 V input-output voltage, and a peak output power is obtained at 80 W. A peak output power of 100 W is reached for input-output voltage of 200- 60 V with an efficiency of 83.5 %. These first results showed good performances for DC-DC converter based on a PR well matched for high-to-low voltage conversion and low power conversion.
