  • Patent number: 10110110
    Abstract: When switching operations of converter cells are stopped due to temporary voltage reduction in an AC system, a voltage determination unit performs determination regarding a voltage of each DC capacitor after a predetermined period has passed, and a charge control unit transmits a charging gate signal, via a gate control unit, to select a converter cell at a voltage level at which a self-feeding circuit of the converter cell is operable. Thus, a DC capacitor of a converter cell whose voltage is lower than the voltage level at which a self-feeding circuit is operable is charged, thereby enabling switching operations of all the converter cells.

  • Patent number: 10035428
    Abstract: A power delivery system for an electric vehicle provides efficient power management for either continuous or intermittent high-performance operation, using a boost stage and an on-board charging circuit. A main battery, configured as a high-capacity power source, supplies power to the electric motor under normal load conditions. An auxiliary boost battery assists the main battery in supplying a high-level current at a higher discharge rate thereby causing the motor to operate in a high-performance drive mode. A charging circuit recharges the boost battery from the main battery during operation of the motor. The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries. In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load. In another embodiment, power management can be based on timed intervals.
