Digital Temperature Control for Power Supply Devices

摘要

A digital temperature control method for power supply ICs is disclosed. The method acts on one or more system variables. For each system variable, the method comprises measuring a temperature; converting the measured temperature to a digitized temperature; comparing the digitized temperature to at least one temperature threshold; selecting a digital control algorithm from a plurality of digital control algorithms and applying the selected digital control algorithm on the controlled system variable associated with the selected digital control algorithm, thereby obtaining a control value; verifying the obtained control value; and applying the verified control value to control the power supply to an external device.
