Core offering

Headspring designs, manufactures, and sells bidirectional power electronics products, including regenerative DC and AC power supplies (biATLAS, biTRITON, biORBIS), SiC/GaN-based power electronics development tools (biRAPID), battery charge/discharge test systems and cell simulators (biAXIA, Atlas Battery), a measurement and control automation OS (biPYXIS), and semiconductor reliability evaluation equipment. The company also provides custom power supply solutions, contract power electronics development, semiconductor evaluation services, and consulting, all built around its proprietary Dual Active Bridge isolated bidirectional conversion technology.

Product overview

Headspring offers a portfolio of power electronics products organized around bidirectional power conversion technology, next-generation semiconductor (SiC/GaN) expertise, and measurement/control automation. The core platform consists of bidirectional DC power supplies (biATLAS, biTRITON) and the biRAPID development tool ecosystem (SiC/GaN inverter circuit blocks, HSDT-KIT-B embedded control software library), which share a common controller architecture. These are complemented by the biPYXIS measurement automation OS for test system integration, and the biORBIS bidirectional AC power supply. For battery and energy storage, the company offers charge/discharge test systems, the biAXIA battery cell simulator, and the smart energy lineup (biPOWER-share grid sharing, biPOWER-ESS storage, biPOWER-BKP UPS, biPOWER-CHG EV charger, and biPOWER-MOB portable storage). The portfolio also includes semiconductor reliability evaluation equipment (power cycle, high-temp/dynamic bias test systems), hydrogen power generation products, and custom power supply / contract development services. The product ecosystem is unified by Headspring's proprietary dual active bridge (DAB) isolated bidirectional technology, enabling modular and scalable configurations across applications from R&D tools to grid-scale energy systems.
