1. A photovoltaic array for use in an electrical power system, the photovoltaic array comprising:

  • multiple photovoltaic modules;

    a voltage converter coupled to at least one of the photovoltaic modules; and

    an over-voltage protection circuit comprising;

    an interface adapted to couple to an output of the voltage converter;

    a spike detector configured to detect a voltage spike in an output voltage of the voltage converter; and

    a voltage control module configured to regulate an output voltage slew rate of the voltage converter in response to an over-voltage signal received from the spike detector.
