Lithium niobate resonators for piezoelectric power conversion
2023Piezoelectric power converters, where acoustic resonators replace the inductors as energy storage elements, promise much higher power density and efficiency than conventional circuits. Recently, lithium niobate piezoelectric resonators have been integrated within power converter circuits, showing good conversion efficiency, thanks to their high quality

Secondary-side resonance for high-frequency power conversion
1986 IEEE Applied Power Electronics Conference and Exposition, 1986A systematic approach is proposed that enables the use of the leakage inductance of the power transformer and a secondaryside capacitor to form a resonant tank for very high frequency power conversion. Several new quasi-resonant converter topologies based on this technique are derived.

Principles of quasi- and multi-resonant power conversion techniques
1991 IEEE International Symposium on Circuits and Systems (ISCAS), 1991Recently developed quasi-resonant and multi-resonant DC-DC power conversion techniques are reviewed. Quasi-resonant converter (QRC) and multi-resonant converter (MRC) topologies are derived from the conventional square-wave, pulse-width modulated (PWM) converters by adding resonant components to achieve zero-current switching (ZCS) or zero-voltage ...

Magnetizing approach for permanent magnets with resonant power conversion
2015 IEEE International Telecommunications Energy Conference (INTELEC), 2015Resonant power conversion is an effective technology for various applications. This paper presents a resonant magnetizing approach, aimed at improving the low power density and cost issues of traditional capacitor-discharged impulse magnetizer. In the method, a resonant tank is established by a series capacitor and inductor.

Series resonant AC-power interface with an optimal power factor and enhanced conversion ratio
IEEE Transactions on Power Electronics, 1986A new method of power pulse modulation with internal frequencies of tens of kHz which is also suitable for multikilowatt power levels is applied to a series-resonant converter system for generating synthesized multiphase bipolar waveforms with reversible power flow.

Large-Signal Characterization of Piezoelectric Resonators for Power Conversion
2024 IEEE Applied Power Electronics Conference and Exposition (APEC)Magnetics are key components of conventional power converters, but they are often the bottleneck to achieving high power density due to their size, weight, and poor performance at small sizes. Piezoelectric devices, when operated in their inductive regime, can serve a purpose similar to that of magnetic components and offer favorable scaling properties

Multi-resonant passive components for power conversion.
2005Semiconductor-device limitations to system miniaturization have receded, but exposed by their improvement numerous "ancillary" barriers which continue to preoccupy nearly every electronics industry. Prominent among these obstacles are package parasitics and heat, which have come to the fore as conventional circuits are applied in modern regimes of ...
