Abstract: In at least one embodiment a system including at least one switch, at least one transformer, a first active bridge and at least one controller. The at least one switch receives a first direct current (DC) input signal from a first DC charging station. The at least one transformer includes a primary side and a secondary side. The secondary side of the at least one transformer is connected to the at least one switch and transfers the first DC input signal. The first active bridge is positioned on the secondary side, the first active bridge generates a DC output signal that supplies one or more vehicle loads. The DC output signal is greater than the first DC input signal and the at least one controller programmed to activate the at least one switch in response to receiving the first DC input signal.

Abstract: A voltage balancing circuit includes a direct-current-to-direct-current (DC-to-DC) voltage converter interconnecting a first battery having a first voltage and a second battery having a second voltage, wherein the DC-to-DC converter transfers electrical power from the first battery to the second battery when the first voltage is greater than the second voltage, and transfers electrical power from the second battery to the first battery when the first voltage is less than the second voltage, and wherein the transfer of electrical power from the first battery to the second battery or from the second battery to the first battery balances the electrical power difference between the first battery and the second battery.

Abstract: A voltage converter includes a converter stage having a direct current to direct current (DC-to-DC) voltage converter, wherein the converter stage receives a first DC voltage and outputs a second DC voltage different than the first DC voltage. The voltage converter also includes a boost pre-stage having a boosting circuit and a capacitor, wherein the boost pre-stage receives a DC voltage from a battery and outputs a boosted DC voltage to the converter stage as the first voltage, wherein the boosted DC voltage is greater than the DC voltage from the battery. The boosted DC voltage of the boost pre-stage output to the converter stage provides fault resistant operation of the converter stage in the event of one or more fluctuations in an operating range of the DC voltage from the battery.

Abstract: A unit for regenerating the heat produced by exhaust gases in movable hearth baking furnaces not altering the operating conditions of the furnace and not causing any damage thereto, either obtaining steam or heating at high temperature diathermic oil to be used for heating the mixtures intended to be used for preparing carbonaceous articles, which unit comprises: a side inlet mounted on the smokestack and provided with an on-off valve and a sector valve placed at the outlet of the smokestack; an exhauster; a control logic; a pressure adjuster; and, a temperature adjuster associated to a heat regenerator of a known type.

Abstract: The invention provides improvements in continuous ring furnaces which have sequentially arranged and communicating chambers and which are used for baking and rebaking carbon articles, wherein a movable bridge member is employed to connect a common smoke channel with a first chamber, so as to draw a portion of smoke flowing through said smoke channel and recycle the same through the furnace.
