Mitsubishi Electric intends to construct a facility for developing and testing middle-voltage direct current (MVDC) distribution at its Power Distribution System Center in Japan.

Located at Marugame in the Kagawa prefecture, the facility will cover around 180m² with a gross floor area of about 500m². It is expected to start commercial operations in April 2016.

MVDC distribution systems can lower power loss during deliveries, which can make related technologies more attractive for businesses focused on sustainable solutions.

Environmentally friendly power distribution systems integrate renewable power sources, such as solar and wind energy, with an electrical accumulator. These usually produce DC power that is then converted to AC, for use.

Communication devices and digital devices usually require it to be altered back to DC. Power loss usually occurs during these repeated conversions, which can be avoided with the use of MVDC systems.

These can thus enable savings by reducing energy loss, offering the scope for using thinner power cables, and facilitate energy transmission over longer distances.

To gather the best DC technologies at the facility, Mitsubishi intends to reevaluate its current equipment, which includes distribution board for data centre energy conservation and high-speed circuits for railway lines.

Mitsubishi Electric will also develop next-generation MVDC technologies at the new centre and ‘communicate their value to consumers,’ the company said.
