Fostering electrical democratization worldwide through its next-generation power semiconductors, with designs one-tenth the size of current devices.

Headspring aims to further expand the use of high-potential, fast-growing smart energy systems, such as solar power, wind power, power storage, and electric vehicles. The company develops and commercializes modular isolated power converters based on next-generation power semiconductors in order to deliver better conversion efficiency and more compact designs at lower prices. Inverters and converters are key foundational technologies for any electronics application like MicroGrid, EV, solar PV, and data centers, which need a high capacity of electrical throughput. Currently, nearly every application utilizing a specialized inverter requires the device to be entirely customized, which is an expensive and lengthy process. Headspring is working toward creating easily combined modular inverter systems which can be parallel and series-connected with scalability, something not currently available, utilizing high-frequency, isolation, and IoT communication technology developed in-house. Headspring is the first to bring to market the next generation of inverters and converters which will help usher in electrical democratization for all.
