摘要
压电变压器(Piezoelectric Transformer,简称PT)的并联连接是提高传输功率的一种有效方法。针对高压电容充电电源这一应用领域,设计了基于压电变压器并联的单开关高压变换器。该变换器采用量子控制模式来稳定输出电压,整个拓扑结构简单,工作可靠。实验结果证明,压电变压器的并联操作可有效提高变换器的输出功率。
Parallel connecting of piezoelectric transformer is an effective way to improve the out power.This paper presents a novel quasi-resonant converter based on parallel connecting PT for high voltage pulse capacitor charging.Quantum-mode control strategy is adopted to stabilize output voltage within the expectant range.The system has the advantages of simple structure and reliability.The design instance is described, the results of reality and calculation are well consistent.
