The technology also can sit in DC-to-DC devices, which are designed to adjust the voltage and minimize power losses.

FORBES: Google-backed Transphorm Raises $25M For Power Conversion Tech

High-voltage DC can carry power over long distances at lower cost than alternating current, but the transformers still cost too much to make the idea widespread.
