タ。[Claims for Utility Model Registration] 1. A series circuit comprising a primary winding of a transformer to which an input voltage is supplied and a switching element, signal generating means for generating a control signal for controlling the switching operation of the switching element, and the transformer. output means for rectifying an alternating current signal generated on the secondary side of the switching element to generate a stabilized output signal; bias means for supplying a bias signal for the switching element; A switching regulator characterized in that it has a control means that performs variable control in response to. 2. The control means is configured to change the magnitude of the bias signal from an initial value to a normal value in response to the output signal rising to a predetermined value. A switching regulator according to claim 1 of the utility model registration claim.
