Mainstream’s power factor correction (PFC) unit is a passive, low-loss system that increases the lifetime and reliability of generators suffering from leading electronic loads. Mainstream is a solutions-oriented research, development, and manufacturing company that has been providing innovative solutions to the U.S. government since 1986.
Mainstream’s low SWaP-C (Size, Weight, Power and Cost) design enables integration on military aircraft with minimal impact on the overall system weight. The passive architecture is a low-cost, high-reliability option that doesn’t generate additional electromagnetic interference. With Phase II prototyping verifying the functionality of the PFC, our goal is to work with government/prime contractors to integrate the PFC into legacy military aircraft and shipboard systems to increase reliability, readiness, and service life while reducing life-cycle costs.
Galley-Scullery Water Conservation System (GSWCS).
Mainstream’s greywater processing system treats ship greywater to levels safe for disposal, reducing the amount of greywater entering the collection holding transfer (CHT) tank, increasing ship mission time, lowering water disposal costs, and preventing the need to retrofit existing CHT tanks. Mainstream is a solutions-oriented research, development, and manufacturing company that has been providing innovative solutions to the U.S. government since 1986. Mainstream’s modular system allows for a unit that fits in multiple space claims for different ships. The system architecture is built on Mainstream’s Greywater Recycling System for Army Field Kitchens that has demonstrated success. Our goal is to work with the government and prime contractors to demonstrate improved water management and reduced shipboard maintenance and environmental waste.
Mainstream Engineering’s GaN power switch module is a 1.3 kV, 240 A peak, gate drive integrated single phase, three level power module that can switch in excess of 200 kHz. This module is specifically designed for 6 MW/m3 450 VAC, and 1 kV DC power conversion systems. The switch module can handle 70% more output power than a similarly rated IGBT module and reduces generated EMI, resulting in system SWaP reductions. Currently, component testing and modeling are being used to transition the GaN switch from a TRL 4 to 6. Mainstream Engineering develops energy conversion systems and components including those in the area of power electronics. Mainstream seeks transition/commercialization partnerships with DRS, L3, GE, LMCO, and Northrop Grumman for the GaN power switch module.
