  • Patent number: 11411510
    Abstract: A direct current/alternating current (DC/AC) inverter system includes a primary DC-DC converter that receives an input DC voltage and a secondary DC/AC inverter. The primary DC-DC converter includes a plurality of switching networks and a plurality of transformers having a plurality of primary windings and a plurality of secondary windings. Characteristically, the plurality of secondary windings is arranged in series to provide a first output and a second output. A resonant LC circuit is connected in series with the first output and the second output. A rectifier rectifies an AC voltage between the first output and the second output to form a first rectified output. The secondary DC/AC inverter receives the first rectified output or filtered output thereof and provides a high voltage AC output. A controller mediates switching of the plurality of switching networks.

  • Patent number: 11313917
    Abstract: An electric current sensor for detecting a leakage current from an electric vehicle charger. The current sensor includes a magnetic core having a gap formed therein, a first conductor wound around the magnetic core to form a first coil, a second conductor wound around the magnetic core to form a second coil, and a tunnel-magnetoresistance (TMR) sensor element arranged in the gap of the magnetic core. A difference between electric current flow in the first and second conductors produces a magnetic field in the gap of the magnetic core proportional to a leakage current, and the magnetic field produces a voltage in the TMR sensor element indicative of a value of the leakage current.

  • Publication number: 20220095811
    Abstract: A seat assembly with an adjustable head restraint assembly capable of being adjusted based on an approximate stature or spatial location of an occupant in the seat assembly. A seat assembly may include a sensor in the seat to detect if an occupant is present. The sensor may include a plurality of bladders and pressure sensors, a radar system, or a neuro-monitoring sensor. The sensor may send a signal to a controller indicating the presence of an occupant. The controller may approximate the size and/or spatial location of the occupant and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to an in-use position. The controller may determine that an occupant is not present and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to a non-use position.

  • Publication number: 20200198481
    Abstract: A system for a charging a vehicle is provided. The system includes a power generating device and one or more controllers. The power generating device is configured to generate a first energy signal corresponding to a requested amount of voltage for one of a vehicle and a base pad during a vehicle charging operation. The controller is configured to receive a request indicative of the requested amount of voltage to provide to the vehicle during the vehicle charging operation and to control the power generating device to generate the first energy signal based on the request. The controller is further configured to determine a resonant frequency of the first energy signal and to adjust a capacitance of a tuning capacitor network based on the determined resonant frequency to compensate for a distance variation between a vehicle pad and the base pad during the vehicle charging operation.

  • Patent number: 10594157
    Abstract: A wireless charger output protection system and method is provided for protecting a battery in an electric vehicle during wireless charging. A wireless power transfer system includes a wireless charger on the electric vehicle side that receives power wirelessly from a charging base. The wireless charger output protection system and method shuts down the wireless charger output and dumps energy in a receive antenna (e.g., a vehicle pad) when a charging error is detected before the charging base can be shut down. The system and method employs a zero-voltage switching (ZVS) scheme to shut down the wireless charger output, in response to the charging error, to protect the switching devices and enhance overall reliability.

  • Patent number: 10483772
    Abstract: A wireless charger output protection system and method is provided for protecting a battery in an electric vehicle during wireless charging from both a desired power source and a stray power source. A wireless power transfer system includes a wireless charger on the electric vehicle side that receives power wirelessly from a charging base. The wireless charger output protection system and method shuts down the wireless charger output and dumps energy in a receive antenna (e.g., a vehicle pad) when a low-voltage battery connected to the wireless charger is lost. The wireless charger output protection system and method also shuts down the wireless charger output and dumps unwanted energy in the receive antenna (e.g., a vehicle pad) when power is transferred from a stray power source coupled to the receive antenna.
