About BRUSA Technology
BRUSA Technology AG is a development service provider and manufacturing partner specializing in e-drives and power electronics, headquartered in Buchs in the St. Gallen Rhine Valley (Switzerland). Founded in 2023 as a spin-off of BRUSA Elektronik AG, the company offers services along the entire product life cycle: system design and requirements engineering, simulation, software, hardware, PCB and mechanical development, testing, industrialization, prototype as well as small and medium series production of electronic assemblies, and after-sales services. The portfolio includes drive components for 48-, 400- and 800-volt systems (inverters, e-motors, on-board chargers, DC/DC converters, VCUs, PDUs, battery/BMS) as well as complete e-powertrain kits with power outputs from 20 to 400 kW. Series production and final testing take place at the Sennwald site; a partner network is available for high-volume production. Customers come from automotive/e-mobility, off-highway, cable cars, electric boats, motorsport, aviation and stationary energy conversion, including Bosch Rexroth, Bartholet, X Shore and Applus IDIADA.
