The goal of the power conversion module is to reduce the waste created when electricity from the grid is converted into usable electric power. Transphorm's GaN solution cuts wastage by up to 90% and also simplifies the design and manufacturing of a wide variety of electrical systems and devices. In recent months Transphorm has increased its customer base by 50% and expanded its operations by 30% to accommodate rising demand.

And thanks to the Series D round of financing this expansion plan looks set to continue, with the additional funds used to increase the company’s production facilities and accelerate product development.
