Exploration of energization and radiation in geospace (ERG): challenges, development, and operation of satellite systems

Publikováno v: Earth, Planets and Space, Vol 70, Iss 1, Pp 1-20 (2018)

Abstract The exploration of energization and radiation in geospace (ERG) satellite, nicknamed “Arase,” is the second satellite in a series of small scientific satellites created by the Institute of Space and Astronautical Science of the Japan Aer

Autor: Masatoshi Uno, Toshiki Shinohara, Yota Saito, Akio Kukita

Publikováno v: Energies, Vol 12, Iss 10, p 1919 (2019)

Partial shading often appears on photovoltaic (PV) strings installed in small space probes, such as moon exploration rovers, due to their body structures, reducing the power yield of PV strings. Such partial shading issues can be precluded by differe

String-to-Battery Voltage Equalizer Based on a Half-Bridge Converter With Multistacked Current Doublers for Series-Connected Batteries

Autor: Akio Kukita, Masatoshi Uno

Publikováno v: IEEE Transactions on Power Electronics. 34:1286-1298

Voltages of series-connected batteries gradually become imbalanced due to nonuniformity in terms of not only battery characteristics but also self-discharge rate that is significantly dependent on temperature. In large-scale energy storage systems, a

PWM Switched Capacitor Converter With Switched-Capacitor-Inductor Cell for Adjustable High Step-Down Voltage Conversion

Autor: Akio Kukita, Masatoshi Uno

Publikováno v: IEEE Transactions on Power Electronics. 34:425-437

High step-down voltage conversion is necessary to bridge the voltage gap between main power converters and low-voltage auxiliary electronics in power conversion systems. Switched capacitor converters (SCCs) are an attractive candidate as a high step-
