Patent ID: 7834678

Claim:
A method of driving a circuit arrangement with at least one first electrical device and at least one second electrical device connected in series therewith, by means of a semiconductor switch for controlling said first electrical device, the semiconductor switch comprising at least a gate (g), a source (s) and a drain (d), and connected in parallel with said first electrical device by means of the drain and the source, wherein said second electrical device is present downstream of said first electrical device and said semiconductor switch, in the direction of a current flow when the circuit arrangement is in use, the method comprising providing a first control signal between the gate (g) and the source (s), that switches the semiconductor switch, in order to control the first electrical device; providing a second control signal to control the second electrical device, the second control signal being determined in dependence on the first control signal, wherein providing the first control signal comprises providing a resistive element between the gate (g) and the source (s) and providing a current signal through the resistive element, and wherein the second control signal is determined in dependence on the value of the current signal.
