<p>A cooling device controller for controlling a cooling device is provided. The cooling device controller includes: a capacitor for supplying an output voltage through a first terminal; a first switch between a first input terminal and the first terminal of the capacitor; a predetermined reference voltage applied to the first input terminal; a second switch between a second input terminal and the first terminal of the capacitor, wherein a temperature-sensing voltage is applied to the second input terminal, the temperature-sensing voltage varying according to a first sensed temperature; and a switch controller to receive a first voltage waveform having a duty ratio, the duty ratio dependent on a second sensed temperature, wherein the switch controller is operable to turn on and off the first switch and the second switch according to the duty ratio.</p> |
