1. A switched power converter for a recreational vehicle, said switched power converter producing a stable DC output voltage at a power converter output for connection to a battery, the power converter comprising:

  • a switched power supply including a switch, at least one energy storage component producing a regulated, stable DC voltage, and an AC\DC converter;

    a controller generating a switching control signal for controlling said switch to selectively supply energy to said at least one energy storage component; and

    overvoltage protection circuitry, connected to an output of said AC\DC converter, for protecting said switch and said energy storage component from damage resulting when a voltage level at the output of said AC\DC converter reaches a predetermined limit by reducing the voltage applied to said switch from said AC\DC converter when the output of said AC\DC converter reaches said predetermined limit.
