Adaptive timing temperature control circuit

摘要

An adaptive timing temperature control circuit to control power to an output in accordance with the power which was previously delivered to the output during a prior period of time. Output power is furnished to the output circuit while a first capacitor is charged by a constant current generator to terminate the output power when the charge on the first capacitor exceeds a predetermined value. A second capacitor begins to charge when the output power is terminated for storing a charge in relation to the time since the previous output. The second capacitor is connected for controlling the current output of the constant current generator to vary the time required for the first capacitor to exceed the predetermined charge. The circuit compensates for heat build-up in the output without the need of heat sensing devices.
