Abstract

PURPOSE: A constant voltage element is connected between the both terminals of a photocoupler light receiving element in order to keep the value of voltage between the terminals constant, and low conversion efficient photocoupler is used, thereby electrically insulation-separating an input signal source and main circuit.
