Abstract: The circuit receives an alternating voltage (Vac), and includes circuit blocks (3,4) which cause the frequency of the generated arcs to be approximately independent of any amplitude variations in Vac. The arcs are produced using an isolating transformer with its primary winding (L1) connected from the circuit blocks by a series capacitor (C). These control the capacitor charging and discharging to maintain constant amplitude current pulses in the capacitor. The circuit block regulating the capacitor charging and discharging contain constant current source and a switching section.
