Abstract

Power supply apparatus comprises an input for connection to a AC power source, an output for connection to a DC load, a chain comprising a transformer, and a rectifier and smoothing circuit connected in series between the input and the output. A phase chopping arrangement is connected prior to the smoothing circuit in the chain and a phase chopping angle setting arrangement is configured to control a phase chopping angle of the phase chopping arrangement dependent on a phase angle representation stored in the phase chopping angle setting arrangement. A control circuit is configured: to extract a parameter of a signal provided at the output, to compare the parameter with a target, and to provide an adjusting signal for adjusting the phase angle representation stored in the phase chopping angle setting arrangement dependent on the result of the comparison.
