| Summary |
"This paper presents the design and construction of a medium power, synchronous, electronic switch and associated timing and control circuits. The unit described is capable of controlling a 20 ampere resistive or inductive load from a 110/220 volt, 60 Hz excitation source. Thyristors are used as the active switching elements. The period of the on/off switching cycle may be varied from 1/60 second to 8 1/2 seconds. Turn-on and turn-off may occur at independently selected phase angles relative to the reference frequency source. Higher power operation could be obtained easily with minor design changes"--Abstract, leaf ii. |
