Systems, methods, and apparatus for limiting voltage across a switch
Abstract:
Systems, methods, and apparatus for limiting voltage across a switch utilizing voltage clamping circuitry are provided. The voltage clamping circuitry may include a rectifier circuit comprising inputs and outputs, the inputs in parallel communication across operational circuitry; an electronic active switching device in parallel communication with the outputs of the rectifier circuit; and at least one Zener diode in parallel communication with the electronic active switching device. When voltage across the electronic active switching device and the Zener diode meets or exceeds a predetermined value, the current will flow through the electronic active switching device and limit voltage across the operational circuitry to within a voltage clamping circuitry voltage limit.
