Latest Patents

Ard Coenraads holds a patent for a "Method and device for driving a turn-off thyristor." This invention specifies a method for turning a Gate Turn-Off (GTO) thyristor on and off, along with a corresponding driving circuit. The technology involves generating a turn-on current and a holding current from voltage pulses, which are converted into currents using an electric energy store. A key advantage of this circuitry is that the required voltage pulses can be drawn from the same energy source as the pulse needed to generate the turn-off current. The holding current is generated by repeating voltage pulses, with the frequency of these pulses adjustable based on the gate-cathode voltage.
