装置。゛When the output control element is turned on, a current flowing between the output electrodes is applied to the primary winding of the converter transformer, and during the on period of the output control element, the energy stored in the secondary winding of the converter transformer is transferred to the load through a smoothing capacitor. supply,
The fluctuation in the voltage across the smoothing capacitor is detected by an error detection circuit, and when the output control element is turned on, the current flowing through the primary winding is controlled to maintain the voltage across the smoothing capacitor constant. (In an error detection device for a power supply circuit, a peak value of load power consumption is set, and a peak detection signal representing a load fluctuation larger than this set value is applied to the error detection circuit to convert the power supply circuit when the output control element is turned on.) An error detection device for a power supply circuit characterized by suppressing the current flowing through the primary winding of a transformer.
