Abstract: Wireless power transmitting equipment may transmit wireless power signals to wireless power receiving equipment. The wireless power transmitting equipment may have a wireless power transmitter coupled to a wireless power transmitting coil. The wireless power receiving equipment may have a wireless power receiving coil coupled to wireless power receiving circuitry such as a rectifier. Foreign object detection coil arrays may be formed from arrays of metal traces on printed circuit substrates that overlap the wireless power transfer coils. Control circuitry in the transmitting equipment and the receiving equipment may monitor signals from foreign object detection circuitry that is coupled to the coil arrays. The foreign object detection circuitry may produce in-phase and quadrature signals that are indicative of whether a foreign object is overlapping a foreign object detection coil array.

Abstract: An electrical system can include a first bidirectional AC-DC converter having an input couplable to a grid connection and an output couplable to a battery and a second bidirectional AC-DC converter having an input couplable to the grid connection or a convenience outlet and an output couplable to the battery. The electrical system can further include a controller that controls the first and second converters to operate in a plurality of modes including a two-stage charging mode in which the first and second converters operate in a forward direction to charge the battery, a single-stage charging mode in which the first converter operates in a forward direction to charge the battery and the second converter operates in a reverse direction to power the convenience outlet, and a non-charging mode in which the first converter is idle and the second converter operates in a reverse direction to power the convenience outlet.

Abstract: An energy storage system can include a battery, a power converter comprising a first plurality of switching devices coupled to the battery and a second plurality of switching devices coupled between the first plurality of switching devices and an AC power system, and control circuitry that determines whether the AC power system is a single/split phase system or a three phase system and operates the first and second pluralities of switching devices accordingly. The control circuitry can include a microcontroller and a plurality of voltage sensors each configured to monitor a magnitude and a phase of a voltage to allow the control circuitry to determine whether the AC power system is a single/split phase system or a three phase system and whether the AC power system is connected with a line to line or line to neutral fault condition.

Abstract: There is provided a clamp circuit for high speed switching devices. The clamp circuit comprising: a clamp switch configured to clamp a voltage at the drive terminal of a switching device and a NOR gate configured to drive the clamp switch. A drive signal of the clamp switch is substantially complementary to a drive signal of the switching device. The NOR gate provides at least a portion of a delay between switching transitions of the switching device and switching transitions of the clamp switch.

Abstract: A switching system can include a main switching device configured to switch a voltage, a gate driver having an output coupled to a drive terminal of the main switching device and configured to deliver a drive signal to the main switching device, and a clamp circuit. The clamp circuit can be coupled to the drive terminal of the main switching device. The clamp circuit can include a logic gate configured to drive a clamp switching device coupled to and configured to clamp a voltage at the drive terminal of the main switching device. A drive signal of the clamp switching device can be substantially complementary to the main switching device drive signal. The logic gate can provide at least a portion of a delay between switching transitions of the main switching device and switching transitions of the clamp switching device.
