Abstract

PURPOSE:To execute an electric conduction proportional control by optimum pulse width, by providing a modulating means for executing suitably a pulse width modulation with respect to an output signal from a comparator for comparing a reference voltage outputted from a reference voltage generator, and an output voltage corresponding to a temperature and other physical output value, outputted from the side of an apparatus to be controlled. CONSTITUTION:The titled circuit is provided with a reference voltage generator 1 for outputting a reference voltage which is varied, based on a digital signal, a comparator 14 for comparing this reference voltage, and an output voltage corresponding to a temperature and other physical output value, outputted from the side of an apparatus to be controlled, and modulating means 15, 9 for executing suitably a pulse width modulation with respect to a compared output signal. On the input side of this reference voltage generator 1, a storage means 3 in which a control signal corresponding to one or plural reference set voltages determined in advance has been stored, and a sequential comparison type resist means SAR6 for generating a bit code signal varied successively, based on an output signal from the comparator 14 are provided through a switching means 7. In such a way, an optimum electric conduction proportional control can always be executed.
