TRANSISTORIZED VARIABLE DUTY CYCLE D. C. VOLTAGE REGULATOR
Abstract
The specifications of a missile's power supply require that a variation of output voltage of within .1% be maintained from an unregulated input voltage varying as much as 20% from its quiescent value, output load variation of .1 to .4 amperes, and an efficiency equal to or better than a series regulator. This is a report of experimental and analytical investigations of the factors influencing the efficiency of a variable duty cycle transistorized regulator designed to meet these specifications. Basic to the theoretical efficiency of this type of regulator is the relation: duty cycly = conduction time divided by total period, where conduction time is the interval during which current is passed through a low loss inductor in series between the source and load. The load voltage, before final filtering, controls the conduction time through appropriate feed-back circuitry. A discussion of the required and acceptable circuitry and a summary of the characteristics of the regulator are included.
