  • Patent number: 11374423
    Abstract: A battery charger includes a plurality of rectifier, a plurality of switches respectively for the plurality of rectifier elements, a zero-crossing detector, a switch controller, and a detection reference changer. The plurality of rectifier elements rectify AC voltages of three phases output from a power generator. The plurality of rectifier elements, in an off-state, causes the plurality of rectifier elements to rectify the AC voltages to charge a battery. The plurality of rectifier elements, in an on-state, causes the AC voltages to be short-circuited to a negative side of the battery. The zero-crossing detector detects zero-crossings of the AC voltages. The switch controller outputs, based on the zero crossings, a gate signal for turning on and off the plurality of switches. The detection reference changer changes a reference for the zero-crossing detector to detect the zero crossings.

  • Patent number: 11362528
    Abstract: Mitigation of audible output of one or more components in a charging circuit. A charging circuit may include a mitigation controller operative to monitor a frequency of voltage at an input of a charging circuit. The frequency of the voltage at the input node may result in a mitigation condition associated with audible output of one or more components of the charging circuit. In response to detection of the mitigation condition, the mitigation controller may temporarily disable the supply of power from charging circuit to a system load to mitigate (e.g., potentially eliminate) audible output of the circuit. During a time in which the charging circuit is disabled from supplying power to the system load, a battery of the device may supply power to the system load.
