RESEARCH DIRECTED TOWARD THE STUDY OF LINEAR AMPLIFICATION USING SWITCHES
Abstract
Research is described on the use of switches as power amplifiers. The switch is controlled by a signal to produce a duration modulated pulse train which is then passed through a low pass filter to recover the amplified signal. The method is capable of high efficiency in conversion of d-c source power to signal power, the efficiency approaching 100% with lossless switches in the proper circuit. The distortion is low if the pulse repetition rate is sufficiently higher than the cut off frequency of the filter and if the signal modulating the pulse train falls in the filter pass band. (Author)
