Abstract

PURPOSE:To output constant-voltage, by turning off and thyristor by an output of a comparing circuit when output voltage of the thyristor has exceeded prescribed voltage, and turning on the thyristor by the output of the comparing circuit when the output voltage of the thyristor does not exceed the prescribed voltage. CONSTITUTION:This electric power supplying circuit is provided with a thyristor 9 inserted into a transmission line of rectifying voltage, a constant-voltage circuit 13, and a comparing circuit 10 for comparing the thyristor with prescribed voltage decided by the circuit 13. In this state, for instance, when total voltage of base-emitter voltage of a transistor TR10, a voltage drop of a diode 14 and gate-cathode voltage of the thyristor 9, anode-cathode voltage of the thyristor 9, and rectifying peak output voltage are denoted as VT, V9 and V8H, respectively, voltage V0 across a capacitor 15 becomes V8H-V9 in case of a circuit having no load. Subsequently, in case when there is a load 16, the voltage V0 gradually drops due to the load 16, and when the voltage V0 drops V13-VT or below, TR10 is turned on, the thyristor 9 is turned on, the capacitor 15 is charged, and finally, output voltage is held at V8H-VT.
