Abstract: A programmable DC-TO-AC voltage converter for converting a DC voltage signal provided across two DC voltage terminals to an AC voltage signal having predetermined characteristics. The system includes an AC voltage terminal; a first switch connected between the AC voltage terminal and one of the DC voltage terminals; a second switch connected between the AC voltage terminal and the other of the DC voltage terminals; and a bistable switching circuit coupled to the first and second switches for operating the first and second switches to alternatively connect either the one DC voltage terminal or the other DC voltage terminal to the AC voltage terminal in an alternating high frequency sequence to provide a high frequency pulsed voltage signal at the AC voltage terminal.
