20120307527 | DC-DC CONVERTER FOR ELECTRIC POWER USING A DC ELECTRIC POWER SOURCE - The converter comprises an inverter and a conversion unit in which a transformer powers a controlled rectifier formed by saturable inductors and power diodes. According to the invention, a series reactive circuit associated with the transformer co-operates with the controlled rectifier for the phase displacement of the voltage applied at the primary of the transformer in relation to the current flowing therethrough. The phase displacement is regulated by a control voltage as a function of the variations in the output voltage of the converter. | 12-06-2012 |
20120314452 | METHOD FOR DC-DC CONVERSION USING A DC ELECTRIC POWER SOURCE - The converter comprises an inverter powered by a DC current source. The inverter powers a conversion unit operating on the basis of controlled magnetic switching obtained by means of power diodes and saturable inductors. A regulator can be used to produce a control voltage that is a function of the output voltage which is regulated with the injection of the control voltage into the circuit comprising the smoothing inductors. According to the invention, during each operating cycle, one of the power diodes is locked when the other power diode switches to conduction mode, such as to create a phase displacement between the input voltage of the conversion unit and the input current of same. The phase displacement angle is a function of the control voltage. | 12-13-2012 |
