Electronic parts handling equipment, as well as mounting structure circuit and Peltier element driving method, of the Peltier module

摘要

And pulse width control means for controllably increasing or reducing the temperature change of the Peltier element does not exceed a predetermined temperature gradient, the pulse width of the pulse signal, on the basis of a pulse signal having a pulse width controlled by a pulse width control means, the Peltier element with a switching means for ON / OFF control of the drive current supplied to, and to limit the current rate of change of power supplied to the Peltier element. It can be can be a result, it is possible to suppress a sudden change in the expansion rate and contraction rate of the Peltier element each part, thereby reducing the stress applied to the Peltier element to maintain a long life in the Peltier element to have.
