Where fixed-ratio converters fit in high-power delivery systems
Fixed-ratio converters are often the best way of minimizing the electrical current sent over significant distances in the interest of better power efficiency. Phil Davies Vicor Corp. The vast majority of electromechanical or semiconductor loads require stable dc-dc voltage conversion and tight regulation to operate reliably. The dc-dc converters that perform this function are commonly […]
The move to synchronous power supplies in smart factories
The need for high efficiency is pushing industrial power supplies toward synchronous topologies that minimize the use of external heat sinking and cooling. Anthony “Thong” Huynh, Maxim Integrated Buildings, factories, and industrial equipment are getting more space-efficient, driving a move toward miniaturizing the underlying components that enable intelligence and automation. This trend challenges the power […]
