Abstract:
1. A DC-DC converter intended to convert the electricity provided by an energy source delivering a first direct voltage and a first direct current having first respective values into output energy at a second direct voltage and a second direct current having second respective values, said converter including: an inverter powered by said energy source and intended to create alternative energy at a third voltage and with a third current, a conversion unit intended to deliver said output energy, and a regulator associated with said conversion unit to regulate said second voltage, said conversion unit having a transducer powered by said inverter and feeding into a controlled rectifier intended to provide said second voltage, said controlled rectifier including two serial circuits with opposite conduction directions each made up of a power diode and a saturable induction coil, said saturable induction coils magnetically controlling, during each cycle of the third voltage delivered by said inverter, the beginning- and end-of-conduction moments of said power diodes, and said regulator being connected to analyze said second voltage of said output energy and, as a function of that analysis, to create a control voltage intended to regulate said second voltage, and said controlled rectifier also including two regulating diodes connected to inject said control voltage respectively into the connection nodes between the power diode and the saturable induction coil of said serial circuits of said controlled rectifier, said converter being wherein it also includes a reactive serial circuit associated with said transducer and cooperating with said controlled rectifier to phase-shift said third voltage relative to said third current, and in that said control voltage regulates the phase shift between them as a function of the alternatives of said second voltage.
