Latest Patents

Claudio holds a patent for a transformer isolated drive circuit. This invention features a transformer that is driven with a high-frequency Pulse Width Modulated (PWM) signal. The PWM carrier supplies the necessary power for high gate current pulses, while varying duty cycles control the 'on' or 'off' state of the power device. The design prevents transformer saturation by sensing primary current and resetting it to zero once per PWM cycle. This technology allows for high pulse currents for rapid switching without the need for auxiliary power supplies. Additionally, it includes provisions for fast output current limiting, essential for short circuit protection.
