    Abstract: A power converter includes an unfolder with an input connection with three terminals that connect to a three-phase AC power source and that has an output connection with a positive terminal, a negative terminal and a neutral terminal. The unfolder unfolds the bipolar AC voltages into two unipolar piece-wise sinusoidal DC voltages offset from each other by a half of a period. The power converter includes a three-input converter that produces a DC voltage output across output terminals. The three-input converter includes a positive input connection connected to the positive terminal, a negative input connection connected to the negative terminal and a neutral input connection connected to the neutral terminal. The three-input converter includes switches that selectively connect a voltage to the positive, negative and neutral input connections across a primary transformer winding of a transformer. A secondary transformer winding is connected to the output terminals through a rectification section.

    Abstract: The systems and methods described herein are directed towards a solid state pumping system that utilizes an electric field applied across a channel formed within the solid state pump to move electro-rheological (ER) fluid from an inlet fluidly coupled to a first end of the channel to an outlet fluidly coupled to a second end of the channel. The solid state pumping system may include first, second and third plate with the second plate disposed between the first and third plate. The second plate may include a channel having first and second circuits coupled to opposing sides of the channel. In an embodiment, in response to a voltage applied thereto, the first and second circuits can provide an electric field voltage across the channel such that in response to the electric field voltage the ER fluid moves from the first end to the second end of the channel.

    Abstract: An apparatus for inductive power transfer (“IPT”) includes an active bridge section with input terminals that receive power from a constant current source, where the active bridge section operates at a fixed switching frequency, a primary resonant capacitor connected in series with an output terminal of the active bridge section, and a primary IPT coil connected in series with the primary resonant capacitor, where power is transferred wirelessly between the primary IPT coil and a secondary IPT coil, and the secondary IPT coil is connected in series with a secondary resonant capacitor, which is connected in series with an output rectifier section that receives power from the secondary IPT coil and comprising output terminals for connection to a load. The apparatus includes a controller that regulates output voltage to the load, where the controller regulates output voltage to the load by controlling switching of the active bridge section.

    Abstract: An apparatus for zero voltage switching includes a ZVS assist circuit connected between a switching node and a negative connection of a converter. The switching node is located between first and second switches of a switching leg of the converter. The converter is fed by a constant current source and feeds a constant current load. The ZVS assist circuit includes a ZVS inductance, a first ZVS switch that allows current through the ZVS inductance to change a voltage of the switching node to a condition for zero voltage switching of the first switch of the switching leg, and a second ZVS switch that allows current through the ZVS inductance to change the voltage of the switching node to a condition for zero voltage switching of the second switch of the switching leg. Current through the first ZVS switch is opposite current through the second ZVS switch.

    Abstract: An apparatus for model predictive control (“MPC”) is disclosed. A method and system also perform the functions of the apparatus. The apparatus includes a measurement module that receives battery status information from one or more sensors receiving information from a battery cell, and a Kalman filter module that uses a Kalman filter and the battery status information to provide a state estimate vector. The apparatus includes a battery model module that inputs the state estimate vector and battery status information into a battery model and calculates a battery model output, the battery model representing the battery cell, and an MPC optimization module that inputs one or more battery model outputs and an error signal in a model predictive control algorithm to calculate an optimal response. The optimal response includes a modification of the error signal.

    Abstract: An apparatus for zero voltage switching is disclosed. A system and method also perform the functions of the apparatus. The apparatus includes an MCT region module that defines a minimum current trajectory (“MCT”) for operation between a maximum positive power output to a maximum negative power output of a bidirectional DC-to-DC converter. The converter includes a dual active bridge series resonant converter. The MCT defines a boundary between a zero voltage switching (“ZVS”) region and a hard switching region. The apparatus includes an offset module that defines an offset to the MCT, the offset in the ZVS region, and an MCT control module that adjust switching of switches of the converter to maintain operation of the converter in the ZVS region between the maximum positive power output to a maximum negative power output along a trajectory defined by the MCT and the offset.
