Abstract:

The use of switches, operated to produce a duration modulated pulse train, as a linear amplifier are discussed. An analysis of the signal and distortion is presented. It is shown, for a given degree of distortion, that modulating both leading and trailing edges of the pulses equally allows a lower pulse rate relative to the highest signal frequency than if only one edge is modulated. The efficiency of a single switch SPST in converting power supplied into ac signal power has a maximum of 50 for lossless switch and sinusoidal signal. Circuits using 2 ideal lossless switches have efficiencies of 100 independent of signal amplitude degree of modulation. Some experiments with transistor switches are described. Author
