The Anan converter station is located in a seaside area near the Tachibana-bay thermal power plant in Shikoku. The Kihoku converter station is located in an inland area in Honshu. Both

In Japan, Hitachi has extensive experience of back-office systems. With an 80% market share, 100 million cards issued and 50 million individual transactions per day, the system is used to coping with a large number of requirements.

2015-3-31systems include both converters that convert single-phase AC to DC and converter-inverter systems that incorporate an inverter. A feature of Hitachi’s converter-inverter systems is that they use T-shaped three-level converters to minimize power supply harmonics and noise. To make them smaller and more efficient, the T-shaped three-
