Zusammenfassung:	A hairstyling apparatus 400 includes a heater having at least one heating element 102. A sensing circuit 104 determines a voltage of a mains power supply and outputs a signal indicative of the determined voltage. A power electronic converter 116 converts the mains power supply to a heater drive signal for driving the heater at least partly in reliance on the signal. The apparatus may further comprise a heating element drive circuit (132; figure 3), which does not form part of the power converter, for driving the heating element. The converter may be configured to output a fixed output voltage for a range of mains power supply voltages and may be capable of accepting a mains power supply having an AC voltage of 85VAC to 265VAC.
