1. A device for powering a load comprising:
a power input terminal configured to be connected to a power source;
a power output terminal configured to be connected to a load;
a first conduction path connecting the power input terminal and the power output terminal, wherein the first conduction path comprises one or more first thermistors of a first type of thermistor in series with one or more second thermistors of a second type of thermistor, wherein a first resistance of the first type of thermistor responds, to a change in temperature, in an opposite direction than how a second resistance of the second thermistor responds to the change in temperature;
a second conduction path connecting the power input terminal and the power output terminal; and
a switching circuit configured to connect, during a first time interval and via the first conduction path, the power input terminal and the power output terminal and configured to connect, during a second first time interval and via the second conduction path, the power input terminal and the power output terminal,
wherein, at a beginning of the first time interval, one of the first type of thermistor or second type of thermistor has a greater resistance than a corresponding second or first type of thermistor, and
wherein, at an end of the first time interval, the one of the first type of thermistor or second type of thermistor has a lower resistance than the corresponding second or first type of thermistor.
