摘要： A DC-DC power converter (100) that provides increased power density, reduced size, and reduced costs of manufacture. The DC-DC power converter (100) includes first and second input terminals (101, 102), a plurality of output terminals (116, 117), and at least one electrical element (108/109) connected to at least one of the first and second input terminals (101, 102). In the event a first voltage is applied across the first and second input terminals (101, 102), the electrical element (108/109) provides a second voltage having a value between the first voltage value and a reference voltage value. The DC-DC power converter (100) further includes a transformer (110) having a primary winding (111) and a secondary winding (112), and a switch assembly (103–107) operatively connected to the first input terminal (101), the second input terminal (102), the electrical element (108/109), and the transformer primary winding (111). In the event the first voltage is applied across the first and second input terminals (101, 102), the switch assembly (103–107) switchably applies the first, second, and reference voltages across the transformer primary winding (111) to generate at least one third voltage across the transformer secondary winding (112). The DC-DC power converter (100) further includes a rectifier (113) connected between the transformer secondary winding (112) and the output terminals (116, 117).

摘要： A current-fed DC-DC converter has a topology that improves converter performance and operates an input inductor in continuous conduction mode. The configuration and operation of the converter produces reduced requirements for circuit component ratings and leads to faster transient response time than conventional current-fed DC-DC converters. The converter can operate as an apparent current-fed full bridge converter in one stage, and an apparent current-fed half bridge converter in another stage. The input inductor is configured and operated to release stored energy to the load in conjunction with other energy storage components to provide a continuous output current that significantly reduces output voltage ripple, leading to reduced rating requirements and output components. The converter topology permits a portion of the switching stage to operate with no deadtime to further improve circuit responsiveness and efficiency.

摘要： A multiphase switching DC-DC converter generates an output voltage from an input voltage. The converter includes multiphase coupled inductors having lateral magnetic core and non-looping conductors. The currents in conductors of the inductors flow in opposite directions, and therefore, the coupled inductors are inversely coupled and have a relatively low resistance and relatively small core volume. The reduced resistance of the inductor windings combined with smaller volume of magnetic core in the coupled inductors increases energy conversion efficiency and improves transient response of the converter. The coupled inductors can be employed in buck or boost or buck-boost converters, and they can also be used in buck or boost or buck-boost derived converters with isolation transformers.
