功率转换器的小型化需要高效、紧凑的大功率高频无源元件，这仍然是电力电子领域的一个具有挑战性的障碍。在数量级的基础上分析多种能量存储机制，以确定无源元件的潜在替代方案。机械存储方法的高能量密度为广泛使用的液晶谐振提供了一种有吸引力的替代方案。探讨了压电换能，并在开关电容器型电路中的效率和功率处理能力方面将压电谐振器的性能与 LC 谐振器进行了比较。该分析为探索潜在的无源元件技术并将其性能限制与电气无源元件的性能限制进行比较提供了基础。
Efficient and compact high-power high-frequency passive components are required for miniaturization of power converters and remain a challenging obstacle in power electronics. Multiple energy storage mechanisms are analyzed on an order-of-magnitude basis to identify potential alternatives for passive components. The high energy density of mechanical storage methods presents an attractive alternative to the widely-used LC resonance. Piezoelectric transduction is explored and the performance of a piezoelectric resonator is compared to an LC resonator in terms of efficiency and power handling capability in a switched-capacitor type circuit. The analysis provides a basis for exploring potential passive component technologies and comparing their performance limits with those of electrical passive components.
