We are proposing a new 28 VDC to 120 VAC pure-sine inverter that can meet a wide range of Army military electronics needs. Specifically, QorTek will teamed with leading edge WBG power device manufacturer and leading edge packaging and thermal managements solutions developer as to develop and prototype a new advanced performance 2500W inverter comprised of smaller 625W submodules that can be paralleled as to deliver the target output power levels. The benefits of developing a smaller module include the ability to implement smaller planar magnetics, smaller form factor (slightly larger than a standard 1/8th brick converter), and introduce significant reductions in thermal management requirements. Additionally, the overall modular design architecture now directly enables 625W supply access, paralleling several submodules can similarly providing intermediate 1250 W, 1875 W, or 2500 W power supplies. The introduction of WBG power devices in the new modular architecture brings benefits of reduced size/weight and thermal risk reduction. The new design exploits these WBG devices as to obtain very high efficiencies in a compact size solution.
