ABSTRACT:
A direct current supply, making it possible to produce a number of separate regulated voltages from a single regulated supply, constituted by a voltage multiplier with cascade-connected doubler stages. One of the doubler stages, preferably the first, supplies by the connection point of its two rectifiers at least one circuit for generating a complementary d.c. voltage. This generator circuit comprises a variable capacitor connected downstream to two oppositely connected diodes and connected to earth or to a fixed d.c. potential, one directly and the other across a resistor and a capacitor connected in parallel.
