  • Patent number: 11214148
    Abstract: The present invention discloses a distributed high-frequency AC electrical system for the electric vehicle. The system divides all loads of the electric vehicle into four load areas according to their spatial positions. Four high-frequency inverters and four DC input interfaces are contained in the system, with each of the four load areas being configured with one of the four high-frequency inverters, and each of the four high-frequency inverters being configured with one of the four DC input interfaces. One end of each DC input interface is connected to the DC side of the corresponding high-frequency inverter, and the other end is connected to the storage battery of the electric vehicle. Each high-frequency inverter outputs a high-frequency AC bus to supply power for the loads in the corresponding load area, and the four high-frequency inverters are in a parallel operation state through a high-frequency connection point that connects the four high-frequency AC buses.

  • Patent number: 11208063
    Abstract: The present invention includes one or more adjustment units configured to house one or more electric components that affect impedance in an output of power supply parts in a unit housing in which at least a connection portion has a predetermined shape and size; and a unit support part that is disposed inside the power supply part or between the output of the power supply part and loads and that detachably supports the adjustment unit. When impedance of a wire harness on the output side and the loads changes depending on a difference in a vehicle type, sufficient noise reduction is realized only by replacing the adjustment unit to be mounted without changing a configuration of a main body of the power supply part. Since a component and a component number can be used in common regardless of the difference in the vehicle type, cost can be reduced.

    Abstract: A system comprising a high voltage (HV) bank section using capacitors arranged into two banks, a multifilar inductor coupling the HV bank to a service voltage (SV) bank section and load through a charging circuit charging the SV bank from a more fully charged bank until the charging bank is depleted, and a switch switching, from the depleted bank to the other bank of bank to charge the SV bank. The charging circuit then charging the depleted bank by a power supply as the other HV bank charges the SV bank. A supervisory controller controls the switch to repeat switching and charging between the two banks for a defined period. The capacitors may be supercapacitors having a capacitance on the order of 1 to 10 MegaJoules.
