Patent number: 6738267Abstract: A piezoelectric transformer converts a first voltage, supplied from a voltage source, into a second, different, stabilized voltage by a DC/AC converter followed by a rectifier connected in cascade to a filter. The DC/AC converter block includes a driver block followed by the piezoelectric transformer, such that the driver block feeds the piezoelectric transformer with a pulse train (21) the frequency of which coincides with the switching frequency (F1) of switching elements included in the driver block. The switching frequency (F1) is less than a resonant frequency (FR) of the piezoelectric transformer; for example, the switching frequency is a sub-harmonic of the resonant frequency (FR).Type: GrantFiled: July 19, 2002Date of Patent: May 18, 2004Assignee: AlcatelInventors: Jose Andres Navas Sabater, Mercedes Rivas Saiz, Pedro Alou Cervera, Roberto Prieto Lopez, Javier Uceda Antolin, José Antonio Cobos Marquez

Patent number: 5867378Abstract: AC/DC power converter device comprising a full-wave rectifier (R) the output of which is applied to a direct current module which has two outputs: the main output is connected to the load via a capacitor (C1) which transfers a first power level (P1), and the auxiliary output is formed by a capacitor (C2) and a direct current converter (DC) which stores a second power (P2) and transfers it to the load during the full cycle of the input power wave (PE). As a result the second power level (P2) is continuously topping up the first power level (P1).Type: GrantFiled: June 9, 1997Date of Patent: February 2, 1999Assignee: Alcatel AlsthomInventors: Oscar Garcia Suarez, Jose Antonio Cobos Marquez, Javier Uceda Antolin, Salvador Ollero Velasco, Enrique De La Cruz Moreno
