Abstract
Synchronized mechanical switches are configured to support electrical switching circuits operating at frequencies equal to or higher than the frequency of the primary AC power supply. Due to near perfect impedances of mechanical switches as well as accurate timing control mechanisms, the mechanical switching circuits provide timely electrical connections to the terminals of the primary AC power supply to generate proper waveforms suitable to power next stage electrical circuits without the need to use semiconductor devices.
