Thermoelectric cooler with inrush current control
Systems and methods for controlling a thermoelectric cooler (TEC) in an optical transceiver. A TEC system includes a processor that interacts with a power supply and a TEC controller to prevent inrush current. The power supply is switched by the processor and turned on only at a particular time. The power supply has a relatively large time constant such that it ramps slowly to its full value. In the meantime, the processor and TEC controller cause the temperature to ramp to a target value by repeatedly incrementing or decrementing a target value over time and by controlling when the maximum available voltage can be applied to the TEC.
