Abstract

A voltage clamp circuit (100) comprises an input portion (102) arranged to receive an input voltage at an input terminal. The input portion comprises a clamp diode (D3, D4, ... Dn) having an anode connected to the input terminal. A first terminal of a switching element (Q5) is connected to a cathode of the clamp diode (D3, D4, ... Dn), and a control terminal of the switching element (Q5) is connected to a reference node (Vref). A resonant tank portion (108) comprises an inductor (L2) and a capacitor (C2) connected in series at a resonance node (Vres). The resonance node (Vres) is connected to a second terminal of the switching element (Q5). The capacitor (C2) is connected between the resonance node (Vres) and the first terminal of the switching element (Q5). The inductor (L2) is connected between the resonance node (Vres) and an output terminal of the voltage clamp (100). The switching element (Q5) is arranged such that when a voltage at the first terminal of the switching element (Q5) is greater than a threshold value determined by a reference voltage at the reference node (Vref), the switching element (Q5) is turned on.
