Terminal voltage regulation characteristics by static var compensator for a three-phase self-excited induction generator
TL;DR: In this paper, a three-phase self-excited induction generator (SEIG) with squirrel-cage rotor is presented along with its operating performance evaluations for small-scale clean renewable and alternative energy utilizations.
Journal ArticleDOI
Shading and electrical features of a photovoltaic array mounted inside the roof of an east–west oriented greenhouse
Akira Yano,Masayuki Kadowaki,A. Furue,N. Tamaki,Toshihiko Tanaka,Eiji Hiraki,Y. Kato,Fumito Ishizu,S. Noda +8 more
TL;DR: In this paper, the spatial distribution of sunlight energy in an east-west oriented single-span greenhouse equipped with a PV array (12.9% of the roof area) inside a Gothic-arch style roof was assessed.
Proceedings ArticleDOI
Time-sharing boost chopper cascaded dual mode single-phase sinewave inverter for solar photovoltaic power generation system
TL;DR: In this article, a novel prototype circuit topology and control scheme of a high efficiency time-sharing dual mode single-phase sinewave PWM inverter for small-scale solar PV power generation system, which is composed of partially controlled absolute PWM boost chopper in the first power processing stage as well as partially controlled SVM inverter in the second processing stage, is presented.
Journal ArticleDOI
Electrical energy generated by photovoltaic modules mounted inside the roof of a north-south oriented greenhouse
Akira Yano,A. Furue,Masayuki Kadowaki,Toshihiko Tanaka,Eiji Hiraki,M. Miyamoto,Fumito Ishizu,S. Noda +7 more
TL;DR: In this paper, four amorphous-silicon photovoltaic (PV) modules were arranged in an arch formation at the northern end of the Gothic-arch style roof of a north-south oriented greenhouse.
Journal ArticleDOI
Smart Charger for Electric Vehicles With Power-Quality Compensator on Single-Phase Three-Wire Distribution Feeders
TL;DR: In this paper, the authors proposed a smart charger for electric vehicles with a power-quality compensator, which consists of four-leg insulated-gate bipolar transistors (IGBTs), and three legs are used for a single-phase full-bridge-based pulsewidth-modulated (PWM) rectifier, which converts power from ac to dc during the battery-charging operation or from dc to ac during battery discharging operation.
