化電源装置。[Claims for Utility Model Registration] An inverter circuit including a transformer and a switch element that switches a DC voltage and applies it to the primary coil of the transformer, an output voltage obtained by rectifying and smoothing the AC voltage obtained at the secondary coil of the transformer. A rectifying and smoothing circuit that obtains the output voltage eo, a pulse width control circuit that detects the output voltage eo and controls the on/off period of the switch element so that the output voltage eo becomes a constant value corresponding to the reference voltage, and the output voltage eo are supplied. In a DC stabilized power supply device equipped with an abnormality detection circuit that detects an abnormality of overvoltage or overcurrent in a load circuit and stops switching operation of the inverter circuit, there is provided a latch that inputs an external shutdown signal and latches the shutdown signal. a circuit means for stopping the switching operation of the inverter circuit in response to the output of the latch circuit; and a reset circuit for resetting the latch circuit when the input voltage signal applied to the inverter circuit becomes zero. A DC stabilized power supply device characterized by being provided with.
