Abstract: This disclosure provides a resonant LLC power converter unit to provide a plurality of power outputs. The power converter unit includes multiple transformers arranged such that at least one primary winding of each transformer is connected in parallel and configured to provide a power output to a secondary that powers one of the plurality of outputs. One of these transformers, or a parallel choke across an output bus, can be used to provide lower power to the output bus during a standby state (i.e., during a light- or no-load condition). The power converter unit includes a first switching section for providing a first power input during normal operation and a second switching section for providing a second power input during no- or light-load conditions.

Abstract: This disclosure describes systems, methods, and apparatus for automatically determining an asynchronous serial data transmission rate at the hardware level of UART devices. The UARTs may transmit a bit sequence comprising two start bits to ensure that the receiving device can accurately measure a period of a first start bit and use this period to set a sampling rate of the data bits.
