Mainstream Engineering develops power electronics technologies for efficient power conversion, control, and management. Our work supports applications that require reliable electrical performance, compact design, thermal management, and dependable operation across government, military, commercial, and industrial systems.
Power electronics energy conversion is becoming commonplace in a plethora of applications, including hybrid electric vehicles, military aircraft, unmanned aerial vehicles, ship power systems, and alternative energy sources (wind, solar, tidal, wave).
At Mainstream, we are developing the power electronics and control algorithms that run these systems, ranging in power from 100s of watts (battery chargers and low-power supplies) to over 100 kilowatts (pulse-power supplies, permanent-magnet motor drives, and point-of-use converters). These new power electronics systems increase the achievable power densities, increase system efficiencies, and enable installation into a growing field of applications.
