Hitachi's power electronics - the key to present-day society

Power electronics refers to technologies related to electrical energy which support our daily lives.All of these technologies contribute to the well-being of society by ensuring a stable supply of electric power. These are four supporting systems which we have developed and are producing.

Power Electronics

Medium Voltage Multi-level IGBT Drives

We use advanced motor control technologies to contribute to quality/productivity enhancement, energy conservation, and stable operations within the steel, water/sewerage, chemical, transportation, and electric power fields all over the world.

Electric railroad transformers

By the Eco rectifier and battery, we will contribute to energy saving and stable power supply of electric railway.

Power control equipment for wind power

Generates high-quality power with the PWM inverter system using IGBT.

Power thyristor valve

By power thyristor valve and STATCOM, we will realize the system stabilization of power distribution.

STATCOM(Static synchronous compensator)

STATCOM is a high-speed control system of reactive power by self commutated type converter device composed of semiconductor devices such as IGBT etc.

HVDC(High-Voltage Direct Current)

Hitachi's track records in Japan for HVDC interconnection.
