Shipboard Power Conversion

"Legacy electronics require 400-Hz power, and need a frequency converter to operate with 60-Hz ship power. A converter is specifically needed for submarine weapon systems. This converter should produce low conducted and radiated emission, should besufficiently cooled, and should deliver a well-regulated output into transient and non-linear loads. DTI will develop a switching frequency converter that meets these specifications. This will be done by using high-frequency switching, well-designedfilters, high-gain feedback with a large phase margin, and mounting all power components on a cold plate. The Weapon Power Converter developed under this SBIR will completely meet the specific power-converter specifications, as well as the Navy's overall need for reliable, safe, and maintainable electronics systems. This approach will also provide acost-effective solution for other frequency converter requirements - in the military, and for commercial applications where frequency conversion is required, such as between 50 and 60 Hz, and various military and commercial aircraft support. Furthermore,the controls developed here, in conjunction with DTI's high-voltage switching technology, are applicable to a wide range of commercial and military power-conditioning and control applications, including power factor correction, VAR compensation, andFlexible AC Transmission Systems."
