化直流電源回路。In a stabilized DC power supply that includes a capacitor and its discharge resistance between input terminals and outputs the input obtained by connecting an unregulated DC power supply to the input connector or terminal as a stable DC power supply, a transistor or a transistor is connected in series with the discharge resistance. A semiconductor element such as a thyristor is connected to the transistor, and includes means for short-circuiting the base voltage of the transistor or the gate voltage of the thyristor through an input connector or terminal, and turning off the discharge current upon connection of the input connector or terminal,
A stabilized DC power supply circuit characterized in that a discharge current is turned on upon disconnection.
