A Major Step in Series Regulators

Power hybrid microelectronic design techniques have been developed to satisfy the requirements of 10-ampere 100-watt series voltage regulators. Application of these new techniques has resulted in a package occupying roughly the same volume as a TO-63 power transistor, yet containing two 30-ampere power transistors, selectable external components, and associated control circuitry.     

High-Density Avionic Power Supply

Dramatic reductions in size and weight have been achieved in the area of signal and information processing. Power conditioning circuits have not kept pace, primarily due to the relatively slow proggress ress in the passive energy storage and transformation devices. A novel converter topology is described that minimizes the task these components must perform and thereby achieve a significant improvement in power supply density.
