PURPOSE:To simplify the structure of a voltage stabilizer by providing tertiary coil of a transformer at the load circuit side and detecting the error voltage by the tertiary coil. CONSTITUTION:The tertiary coil 30c of a transformer 30 to which a supply source for detecting an error voltage is connected directly is provided to thereby detect the error voltage. The followup property of the variation in the output of the tertiary coil 30c to the variation in a load 14 is good, a transistor 6 is controlled by the output, with the result that the DC voltage of the output of a diode 11 is maintained constant. The output of the tertiary coil 30c is simultaneously applied to the base of a transistor 6 through a diode 25 and a resistor 2 as a trigger signal of a blocking oscillation. |
