SynQor DC-DC and AC-DC Converters

SynQor DC-DC and AC-DC Converters

This is a switching power supply that supports a wide input voltage range while achieving high efficiency and compact size. It has a proven track record in battleships, patrol boats, and aircraft carriers.

SynQor's isolated DC-DC converter is a unit-type DC-DC converter that adopts a two-stage power topology structure, accommodating a wide input voltage range while achieving high efficiency and miniaturization. Traditionally, many DC-DC converters faced difficulties in commercialization when accommodating a wider input voltage range than a 2:1 voltage ratio, as their efficiency would drop by 10 to 25% compared to 2:1 units, and their size would increase. However, by developing a two-stage power topology structure that consists of a "regulation stage" and an "isolation stage" within a single unit, SynQor has made it possible to support a wide input voltage range and achieve high efficiency while also enabling package miniaturization.
