  • Touch safe DC powering for remote loads
    Patent number: 11733285
    Abstract: In a line to line fault detection and protection system, a source end power supply supplies power to a remote load over a transmission line and monitors the dynamic behavior of a transmission line power characteristic. If that dynamic behavior is outside a constraint that is actively imposed on the transmission line dynamic behavior by a load end power conditioning system, a possible line to line fault is recognized. The preferred power characteristic is current and the preferred constraint is a maximum rate of change of current drawn from the transmission line by the load end power conditioning system.
    Type: Grant

  • Synchronous rectification of LLC converters based on homopolarity
    Patent number: 11159090
    Abstract: Synchronous rectification methods and algorithms, and polarity sensing techniques, based on the homopolarity cycle concept for conduction loss reduction in LLC resonant converters are provided. In a half bridge rectifier configuration, one of rectifier switches is switched ON when the polarity of the inverter and rectifier voltages are both positive and the other rectifier switch is switched ON when both polarities are negative.
