1. An apparatus comprising:
- a heating element configured to heat a target element;
a temperature sensing device configured to be thermally coupled to the heating element or the target element to provide an output proportional to a temperature of the heating element or the target element to which the temperature sensing device is thermally coupled; and
a controller configured to modulate an amplitude, duration and frequency of individual current pulses of a series of current pulses applied to the heating element, based at least in part on the output of the temperature sensing device.
