Abstract
PURPOSE:To stabilize output voltage by detecting the switching current, supplying it to an error amplifier of a pulse width modulation circuit and controlling the duties. CONSTITUTION:A switching regulator is constituted of a start-up and auxiliary power circuit 1, a drive circuit 2, a pulse modulation circuit 3, a standard voltage source 4 and an oscillation circuit 5. And, a primary winding N5 of a current transformer GT is connected in series between a source S of a switching element Q and an input terminal, and a secondary winding N(b) is wound at the same polarity as that of the primary winding N5 so as to have the same starting of winding. The secondary winding N(b) is connected to an error amplifier of a pulse width modulation circuit 3 through a rectifier diode D4 and resistance R2. According to the constitution, the current of the switching element Q is detected and supplied to the error amplifier of the pulse modulation circuit 3 to compare it with the standard voltage source, and when detection voltage becomes low, a pulse width is widened and operates so as to standardize output voltage.
