摘要:
A heater controller for controlling a heater precisely in the equi-power mode is disclosed. The controller includes a current source, a voltage monitor to detect a voltage drop caused in the heater, and a controller. The voltage drop may be converted to the digital form as refereeing to the first reference, while, the heater current is converted from the digital form as referring to the second reference. The second reference shows substantial temperature dependence, while, the first reference has lesser temperature dependence. The control corrects the temperature dependence of the second reference as referring to the first reference.

公开了一种用于以等功率模式精确控制加热器的加热器控制器。 控制器包括电流源,用于检测在加热器中引起的电压降的电压监视器和控制器。 电压降可以转换为数字形式,作为裁定到第一参考,而加热器电流从数字形式转换为参考第二参考。 第二个参考文献显示了实质的温度依赖性,而第一个参考温度依赖性较小。 控制器将第二个参考的温度依赖性修正为参考第一个参考。
