Abstract (en)
[origin: WO2011036875A1] A cooling control circuit for a Peltier device comprises: a switching device 3; an LC filter 4, 13 connecting between the switching device 3 and the Peltier device 1, the LC filter 4, 13 smoothing an output from the switching device 3; an amplifier circuit 6 amplifying an output from the LC filter 4, 13; and a switching device control circuit IC configured to control an on-state and off-state of the switching device 3 based on a level of an output from the amplifier circuit 6. The amplifier circuit 6 delays and amplifies the output from the LC filter 4, 13 so that a maximum level of the output from the LC filter 4, 13 reaches a level at which the switching device control circuit IC brings a switching device 3 into the off-state.
