Abstract
A power converter is described adapted to be connected to an electrical power source, in particular a voltage source (V.sub.cc), and intended to receive at the input a control signal (A(t)) for the conversion, including a first regulator circuit (L.sub.1, C.sub.1, M.sub.1, D.sub.1) of the pulse width modulation step-down type and an energy recovery-circuit for managing a bidirectional flow of energy from the source to the load and from the load to the source; such an energy recovery circuit may advantageously be implemented using a second regulator circuit (L.sub.2, M.sub.2, D.sub.2) of the pulse width modulation step-up type.
