Abstract: A flight display is described. The flight display includes a display screen, a physical network interface, and multiple processors. The flight display interfaces with the flight deck by way of the physical network interface. The display screen displays images representative of avionics data in response to signals generated by one or more of the processors. The processors also generate command signals causing an actuator of the aircraft to control a flight control surface or a throttle. In this regard, the one or more of the processors perform various automatic flight control system (AFCS) functions. A system is further described including multiple of the flight displays. By hosting the AFCS functions across processors of the multiple flight displays, a level of command integrity may be reached. Furthermore, backups flight displays are available to be reconfigured to perform the AFCS functions.

Abstract: Reduced voltage switching of the primary switch. At least one example is a method comprising: activating, during a first switching period, a primary switch coupled to a primary winding of a transformer of a flyback topology, the activating induces a positive current in the primary winding; deactivating the primary switch and activating a secondary switch coupled to the secondary of the transformer, the activating the secondary switch during the first switching period and for a duration selected based on a signal indicative of negative current from a prior switching period, and the activating the secondary switch results in a positive current through the secondary winding followed by a negative current through the secondary winding; and discharging capacitance of the primary switch by a negative current in the primary winding responsive to the negative current in the secondary winding.

Abstract: During a light load (or no-load) operation of a totem pole power factor correction circuit (i.e., PFC), a pulse width modulation (PWM) controller can operate in a skip mode. Further, the PWM controller may disable portions of the PFC to reduce standby power consumption. In this mode, and in this disabled configuration, the output of the PFC may be peak charged over time to a voltage that could be damaging or destructive. This peak charging results from the PFC circuit's inability to fully charge/discharge EMI capacitors between half cycles of the input line voltage. The present disclosure provides circuits and methods to fully charge/discharge the EMI capacitors to prevent peak charging the output.
