High-Speed Gate Driver Using GaN HEMTs for 20-MHz Hard Switching of SiC MOSFETs
Takafumi Okuda, Takashi Hikihara
In this paper, we investigated a gate driver using a GaN HEMT push-pull configuration for the high-frequency hard switching of a SiC power MOSFET. Low on-resistance and low input c…
Transient Behavior of Redox Flow Battery Connected to Circuit Based on Global Phase Structure
Toko Mannari, Takashi Hikihara
A Redox Flow Battery (RFB) is one of the promising energy storage systems in power grid. An RFB has many advantages such as a quick response, a large capacity, and a scalability. D…
Power packet transferability via symbol propagation matrix
Shinya Nawata, Atsuto Maki, Takashi Hikihara
Power packet is a unit of electric power transferred by a power pulse with an information tag. In Shannon's information theory, messages are represented by symbol sequences in a di…
On the Spectral Equivalence of Koopman Operators through Delay Embedding
Yoshihiko Susuki, Kyoichi Sako, Takashi Hikihara
We provide one theorem of spectral equivalence of Koopman operators of an original dynamical system and its reconstructed one through the delay-embedding technique. The theorem is…
Applied Koopman Operator Theory for Power Systems Technology
Yoshihiko Susuki, Igor Mezic, Fredrik Raak +1
Koopman operator is a composition operator defined for a dynamical system described by nonlinear differential or difference equation. Although the original system is nonlinear and…
