Outline of Final Research Achievements |
The purpose of this research is to systematize theoretically the ultra-high frequency switching technology which enables the frequency of power supplies to be increased from tens of kHz to hundreds of MHz by injecting harmonic currents, and to achieve high efficiency stably by applying optimization design. Specifically, we developed a theoretical analysis model by combining our original optimization design technology and steady-state analysis technology that can handle systems with harmonic components. Using this model, we established a high-precision and high-efficiency design technology that does not require any parameter tuning and established the basic theory of ultra-high-frequency and high-efficiency switching power supply design.
