Abstract

A driver arrangement with overvoltage protection. A control circuit monitors a first output signal responsive to an offset signal which is configured to compensate for an AC mains power ripple in a power factor correction signal or the sum of this offset signal and the power factor correction signal. The power factor correction converter operates in a positive feedback mode using positive feedback responsive to the first output signal. The control circuit and the power factor correction converter (which produces the power factor correction signal) are further configured to override the positive feedback mode and enter a protection mode to restrict the power if a second output signal exceeds a predetermined threshold value, said second output signal being one of the power factor correction signal, the offset signal, and their sum.
