The lab researches power electronics, which changes the form of electricity at will.
AboutAbout the lab
Highly efficient power conversion through circuits and control
The Fujita-Sano Lab researches power electronics, which converts the voltage, current, frequency, and other properties of electricity.
Rather than relying on device performance, the lab aims to make power conversion equipment highly efficient, high-performance, and compact through circuit configurations and control methods.
Power electronics is used in a wide range of fields, including power generation, power transmission, railways, electric vehicles, and home appliances.
The lab is a member of the 'Power Electronics Lab,' which is run jointly by multiple faculty members. The experimental rooms and seminars are shared, while research supervision of students is provided by each faculty member.

ResearchResearch themes
The lab covers power electronics technology broadly, from power semiconductor devices to conversion circuits and systems. The Fujita Lab works on new circuits and control for power converters, and the Sano Lab works on improving power quality in distribution systems and DC transmission for offshore wind power, among other topics.
*Illustrative imageControlling Power Flow Quickly
To actively control power flow in transmission and distribution systems, the lab proposes a power flow controller with a new circuit in which cascaded converters are connected in a hexagonal configuration.
*Illustrative imageOptically Isolated Gate Drive Circuits
This research concerns gate drive circuits that turn semiconductor switches on and off. Using resonance, the method drives the switch with theoretically zero loss, and the lab has realized a circuit that operates on only the small amount of power transmitted by light.
*Illustrative imagePower Conditioners for Solar Power Generation
To realize highly efficient power conditioners even with conventional power semiconductors, without relying on expensive state-of-the-art devices, the lab proposes new circuit topologies and control methods that reduce losses.
*Illustrative imageBidirectional Isolated DC-DC Converters
The lab studies isolated DC-DC converters that can transfer power in both directions, using compact, lightweight medium-frequency transformers. It has demonstrated high-efficiency operation using SiC-MOSFETs.
