Temperature control system with simplified controller and power supply
Patent
·
OSTI ID:7088685
A temperature control system is described for resistively heating an electrochemical cell comprising: current source means for generating an alternating electric current used to resistively heat an electrochemical cell; heater circuit means for connecting the current source means in an electric circuit across at least a portion of an electrochemical cell; a control amplifier generating at an output terminal a control signal having a varying magnitude for varying the power of the alternating electric current generated by the current source means and circuited through the heater circuit means. This is done when the heater circuit means is connected across at least a portion of an electrochemical cell and receiving at an input terminal a compound signal formed from a first component signal related to the difference between an actual temperature of the cell and a desired temperature of the cell and a second component signal related to the control signal outputted by the control amplifier means; and a feedback circuit coupled directly between the output terminal and the input terminal containing at least two circuit legs connected in parallel, one parallel circuit leg containing only a resistance and the second parallel circuit leg containing only a capacitance and a resistance in series.
