Bovine leukemia virus genotype surveillance in cattle at a slaughterhouse in Aichi Prefecture, Japan, in 2019 using polymerase chain reaction combined with restriction fragment length polymorphism
Autor: Jyunjirou Yamagishi, Masaaki Ohshima, Kaori Shimizu, Yuma Sahashi, Yasuo Inoshima, Chieko Muramatsu
Publikováno v: The Journal of Veterinary Medical Science
Polymerase chain reaction (PCR) combined with restriction fragment length polymorphism (RFLP) is commonly used for genotyping bovine leukemia virus (BLV) in slaughterhouses. However, unclassified BLV genotypes have been sporadically reported. To asse

Novel quick backup function for dispersed power source employing AC/DC converter
Autor: Hirofumi Shinohara, Katsuhisa Inagaki, Masaaki Ohshima
Publikováno v: Electrical Engineering in Japan. 165:74-81
In this paper, the authors present the system configuration and control scheme of a dispersed power source equipped with quick backup function, which acts as a dispersed power source when no fault exists in a commercial power network and functions as

A decupled PQ control strategy of voltage-controlled inverters
Autor: Yang Chen, Keqing Qu, Shuuichi Ushiki, Jinlong Wang, Masaaki Ohshima, Jinbin Zhao
Publikováno v: 2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia).
This paper deals with problems caused by high distributed generation penetration and proposes a simple and precise PQ control strategy for voltage-controlled inverters in micro grids. The widely-used current-controlled inverters cannot provide voltag

Evaluation and testing of voltage-controlled grid-connected inverter for high penetration of renewable energy
Autor: Masaaki Ohshima, Yawei Wang, Jianfeng Dai, Shuuichi Ushiki, Haixian Liu, Jinbin Zhao
Publikováno v: 2015 IEEE Applied Power Electronics Conference and Exposition (APEC).
In view of the fact that there are difficulties for traditional current-controlled grid-connected inverter in power decoupling and voltage regulation at point of common coupling (PCC). Voltage-controlled grid-connected inverter can cope with these is

Novel three-phase current-regulated digital PWM and its behavioral analysis
Autor: Eisuke Masada, Masaaki Ohshima
Publikováno v: Electrical Engineering in Japan. 150:62-77
There have been various studies of PWM algorithms for a three-phase voltage-source AC/DC power converter since the analog modulation scheme based on a triangular carrier wave was proposed in the 1960s. The PWM algorithm can be considered the heart of

A Novel Single-Phase UPS Inverter by Error-Tracking Mode PWM Scheme
Autor: Shinzo Tamai, Masaaki Ohshima, Yuushin Yamamoto, Haruyoshi Mori, Fuminori Nakamura
Publikováno v: IEEJ Transactions on Industry Applications. 120:104-111
This paper proposes a novel single-phase UPS inverter modulated by Error-Tracking Mode PWM scheme. An ac voltage regulation scheme which matches the PWM scheme is newly developed in a theoretical way. Since Error-tracking Mode PWM is based on constan

A novel utility-interactive electrical energy storage system making use of electrical double-layer capacitors and an error tracking mode PWM converter
Autor: Michio Okamura, Masahiko Shimizu, Masaaki Shimizu, Masaaki Yamagishi, Masaaki Ohshima
Publikováno v: Electrical Engineering in Japan. 133:52-62
A novel electrical energy storage system interacting with a commercial ac network was designed and experimentally evaluated. It consists of an ac/dc converter modulated by a constantly sampled PWM scheme called Error Tracking Mode and electrical doub
