Abstract

PURPOSE:To enable to simplify the structure of a converting circuit, by obtaining a DC signal by integrating series binary signals by use of a CR circuit. CONSTITUTION:Output voltage of an integration circuit 7 is smoothed by a smoothing circuit consisting of resistances 8a, 8b and a capacitor 8c and is removed of its pulsation. The DC voltage having a level corresponding to the ON-OFF ratio of ON-OFF signals produced by a control circuit 1 is amplified at a DC amplifying circuit 9 and impressed to an air supplying DC motor 10 for driving the same. The motor 10 is disposed in an air supply duct of an air conditioner and controls the flow rate of air to be supplied to a cabin in a vehicle. Therefore, when a one-bit ON-OFF signal is given from the control circuit 1, it is converted into a DC signal at the integrating circuit 7. Thus, it is enabled to simplify the structure of the converting circuit.
