Abstract
PURPOSE: To simplify the configuration of switching regulator by detecting the variation of switching output without a feedback of the output of DC output terminal and requiring no transformer to perform DC insulation between DC output terminal and AC input power supply.
CONSTITUTION: The switching regulator is provided with an input smoothing circuit 30, switching AC converter 31, variation detector 32 and auxiliary power supply 33, the AC converter 31 has a heater 34 which heats according to a current flowing in the switching transistors Q1, Q2, the heat is detected by the heat sensor 35 to generate a voltage output, the detected output is compared with the reference voltage and the voltage difference is amplified. Thus no input transformer is required since the variation detector 32 is insulated from the output terminal 16 in terms of DC and the insulation between the auxiliary power supply 33 and AC power input is unnecessary.
