Abstract: A chopped power supply converter is provided comprising, between the two terminals of a DC power supply source, on the one hand a primary inductance (L.sub.p) in series with a chopping means (Tr) and on the other hand a capacitive divider bridge formed by two capacitors (C.sub.1 -C.sub.2), a secondary inductance (L.sub.s) coupled to the primary inductance (L.sub.p) and whose value with respect to this latter depends on the ratio of the capacitive divider bridge (C.sub.1 -C.sub.2), this secondary inductance (L.sub.s) being connected between the output terminal of the divider bridge and the load (P) through a series diode (D.sub.1) and a parallel capacitor (C.sub.3), and a balancing device (E) for permanently rebalancing said divider bridge.
