    Abstract: Systems and methods for providing automatic short circuit protection in an electrical system via a switching device. In some embodiments, the switching device includes a switching transistor that selectively switches between an open position and a closed position based at least in part on a switching control signal, for example, to facilitate converting electrical power with first electrical characteristics output into electrical power with the second electrical characteristics. Additionally, the switching device includes a protection transistor electrically coupled in series with the switching transistor, in which a constant gate voltage is supplied to the protection transistor to maintain the first protection transistor in the closed position during operation of the power converter; and the protection transistor automatically limits current flow through the first switching device by reducing a gate voltage applied to the switching transistor when a short circuit is expected to be present in the electrical system.
