電圧変換装置。The AC input voltage is rectified and smoothed, and the voltage output through the transformer is rectified and smoothed by switching control of the switching elements to obtain the DC output voltage, and the output side voltage of the transformer is monitored by the control circuit. While controlling the switching ratio of the switching element to obtain a constant DC output voltage, when the AC input voltage is interrupted due to a power outage or the like, a decrease in the output side voltage is detected along with attenuation of the discharge voltage of the smoothing capacitor. A voltage conversion device that maintains a specified DC output voltage for a predetermined period of time by changing a switching ratio, comprising a plurality of terminals for changing the transformation ratio in the primary winding of the transformer, and means for switching and connecting an input voltage to the terminals. The control circuit detects a drop in the output side voltage of the transformer and changes the switching ratio of the switching element, and also monitors the terminal voltage of the smoothing capacitor by the control circuit to detect a drop in the terminal voltage. A voltage conversion device characterized in that the control circuit automatically increases the operating transformation ratio of the transformer by the means for switching and connecting in response.
