25kW SiC-based OPTI Drive
Edit
Mainstream designed, built and tested a 25 kW continuous (35 kW peak), 105 °C liquid cooled, wide-bandgap (WBG) three-phase motor drive. This motor drive is based on a custom SiC module. The motor drive is 99% efficient, weighs only 11.5 lbs, and has dimensions of 11″ x 7″ x 3.5″. Installation into the end application vehicle is also simplified because all electrical and fluid connections are located on the same enclosure face.

Converter
10kW IGBT-based Opti Drive
Edit
Mainstream’s variable frequency drive is a liquid cooled motor drive with an integrated active PFC rectifier for meeting the strict requirements of MIL-STD 461. It can be powered by a 208/230 Vac, 50/60 Hz source (such as the AC grid, a generator, or a tactical microgrid) or modified to operate from a DC source. The motor drive can be used with fluid inlet temperatures from -40° to 70°C and drive AC induction motors or AC permanent magnet synchronous motors using advanced sensorless field-oriented control.

Satellite Space Converter
Edit
Mainstream designed, built and tested a 2.5 kW 3-port isolated dc-dc converter that is modular and scalable for space applications. This unit consolidates a spacecraft’s electrical power system into a single unit by simultaneously interfacing solar panels (250–400 Vdc), a battery bank (40–60 Vdc), and spacecraft loads (28 Vdc). The converter achieves 98.1% efficient (peak) with GaN power semiconductors and utilizes soft switching techniques.
