Abstract
An electric circuit includes a plurality of electric circuit elements. The circuit is prone to creating voltage spikes on a pair of spaced lines. A jumper line connects the pair of spaced lines. A thermoelectric element is connected on the jumper line such that the voltage spike will pass through a hot node on the thermoelectric element. A cool node of the thermoelectric element is positioned adjacent to components which require cooling.
