Abstract
A voltage clamp circuit comprises an input portion arranged to receive an input voltage at an input terminal. The input portion comprises a clamp diode having an anode connected to the input terminal. A first terminal of a switching element is connected to a cathode of the clamp diode and a control terminal of the switching element is connected to a reference node (Vref). A resonant tank portion comprises an inductor and a capacitor connected in series at a resonance node (Vres). The resonance node is connected to a second terminal of the switching element. The capacitor is connected between the resonance node and the first terminal of the switching element. The inductor is connected between the resonance node and an output terminal of the voltage clamp. When a voltage at the first terminal of the switching element is greater than a threshold value the switching element is turned on.
