About

Hiroaki Ota is a researcher specializing in wireless power transfer (WPT) systems, with a particular focus on multiphase and multiload configurations. His work addresses a critical gap in the field: while most WPT research has concentrated on conventional DC-DC systems, Ota has pioneered approaches that enable direct AC wireless power delivery, eliminating the need for additional DC-AC inverters at the receiver end. His most cited work, "Multiphase Direct AC Wireless Power Transfer System: Comparative Proposals Using Frequency and Amplitude Modulations" (2021, 9 citations), presents innovative comparative frameworks using both frequency and amplitude modulation techniques to supply multiple receivers from a single transmitter. Building on this, his earlier feasibility study from 2019 (4 citations) laid the groundwork for multiphase wireless power transfer using frequency modulation, with promising applications in emerging technologies such as in-wheel motors. Ota's research is particularly relevant to the growing demand for wireless power solutions in electric mobility and industrial automation, where compact, efficient, and inverter-free power delivery systems are increasingly desirable. His contributions represent meaningful steps toward practical, next-generation wireless energy transmission architectures.
