Configuration of an inverter for a train
We research and develop "power electronics technologies" for railway inverter such as power devices, drive circuits, and cooling. These are designed for good performance in ecology. And we are not only expanding domestically into bullet-train lines, conventional lines, and private lines but also globally into overseas railway markets.
As regards railways, contact-line power is rectified by a converter and converted to alternating current with the desired frequency. A motor traction is controlled by an inverter frequency. By researching power devices (such as IGBTs) and packaging technology, circuit technology and various power-electronics technologies (such as noise-analysis technology like electromagnetic compatibility (EMC), we develop the smaller inverters. These inverters contribute the high speed trains such as Shinkansen and the comfortable entrainment.
Moreover, we are developing hybrid trains-which apply Hitachi's battery-control technology while combining diesel engines with electric motors-and focusing our research and development on green engineering.
