Emiliano Gudino Carrizales has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11152852
    Abstract: The invention relates to a bidirectional DC/DC converter for transmitting energy between a high-voltage grid (HV) and a low-voltage grid (LV), comprising connections for a high-voltage battery (UHV) and a low-voltage battery (UNV). The converter comprises the following:—one or more transformers (1) for galvanically isolating the low-voltage grid (LV) from the high-voltage grid (HV), an intermediate circuit capacitor (CZK) in the high-voltage grid (HV),—electronic switches (D1 to D4, M1 to M4) for connecting and reversing the polarity of the coil of the transformer (1) on the high-voltage grid (HV) and on the low-voltage grid (LV),—a controller (2) for controlling the electronic switches (D1 to D4),—and a series inductance (W1) in the low-voltage grid (NV).

  • Patent number: 11128225
    Abstract: The invention relates to a DC-to-DC converter with reduced losses due to a reverse-recovery-effect. A transformer is provided on an input of the DC-to-DC converter. Due to said transformer, an electric current which is possibly still flowing can be compensated and thus suppressed to enable a current-less commutation by means of said transformer. This allows electric losses due to a reverse-recovery-effect, in particular in a continuous step-up converter, to be reduced or eliminated.

  • Patent number: 10992235
    Abstract: The present invention relates to a DC-DC converter and to a method for controlling a DC-DC converter with high dielectric strength and reduced power losses. An optimized control of a potential-isolating multi-level half-bridge converter according to a phase-shifted full-bridge configuration with a novel modulation method is proposed.

  • Publication number: 20210082609
    Abstract: The invention relates to a common-mode/differential-mode throttle (1) for an electrically driveable motor vehicle, with at least a core (4) having two limbs (6, 8) oriented so as to be parallel and spaced from one another, with a common-mode induction coil (L1) and with a differential-mode induction coil (L2), wherein the two induction coils (L1, L2) are each wound around one of the two limbs (6, 8). It is provided for the distance between mutually facing winding sections of the two induction coils (L1, L2) to correspond to the distance between the winding sections at least one of the induction coils (L1, L2) on either side of the respective limb (6, 8).
