Abstract: A switching converter circuit includes a voltage regulation loop configured to provide an output voltage (VOUT) based on an input voltage (VIN). The switching converter circuit also includes a 100% mode circuitry coupled to the voltage regulation loop, wherein the 100% mode circuitry is configured to apply an offset to VOUT in response to detecting that VIN is approaching VOUT.

Abstract: A switched power circuit to control a common-mode signal. The switched power circuit includes a first switch and a second switch configured to generate switch mode voltage between a first node and a second node. The switched power circuit further includes a feedback circuit that is configured to detect common-mode voltage generated between the first node and the second node by a first signal generated by the first switch and a second signal generated by the second switch, and incrementally adjust a timing parameter of the first signal to adjust the common-mode signal.

Abstract: A method of operating a power protection system coupled between a power source and a power converter includes producing, by a controller of the power protection system, a driving signal to a cut-off switch of the power protection system to electrically couple the power source to the power converter; detecting, by the controller of the power protection system, a fault condition of the power converter while the power converter is in operation, where the detecting includes detecting, by the controller of the power protection system, that a current flowing through the cut-off switch is above a pre-determined threshold while a gate control signal from the power converter indicates an OFF state for a first current path of the power converter; and in response to detecting the fault condition, turning off, by the controller of the power protection system, the cut-off switch to isolate the power source from the power converter.

Abstract: Electronic circuitry and a method of operating the same to obtain zero voltage switching on both primary switches in a flyback derived single ended asymmetrical half bridge topology, in all the operating conditions, both in continuous and discontinuous mode operation. Zero voltage switching is accomplished through voltage injection and through a combination of the voltage injection and current injection.

Abstract: An improved power converter produces power through a power switch in response to an activation signal that has an on-time and a switching frequency. An on-time signal has a constant on-time and controls the on-time of the activation signal. An error signal indicates that the switching frequency is not equal to a reference frequency. A step up signal and a step down signal are based on the error signal. A count signal is increased in response to the step up signal and decreased in response to the step down signal. An on-time pulse has a duration that is related to a value of the count signal. The on-time pulse controls the constant on-time of the on-time signal and maintains the switching frequency at about the reference frequency.

Abstract: A power converter including at least one switching device is presented. The power converter is configured to convert an input parameter to an output parameter by periodically activating and deactivating the switching device. The switching device includes: (i) a chamber including an ionizable gas; (ii) a cathode and an anode defining a discharge gap disposed in the chamber; (iii) a magnet assembly configured to generate a first magnetic field such that a plasma is maintained in the discharge gap; and (iv) an electromagnet configured to generate, in response to a deactivation signal, a second magnetic field such that at least a portion of the plasma in the discharge gap is disrupted to deactivate the switching device. A method of power conversion and a switching device are also presented.
