Abstract
A switched power converter for a recreational vehicle includes a housing and a switched power supply. The switched power supply has a switch and at least one energy storage component, the switch controlling the supply of power to the energy storage component. The output of the energy storage component is a regulated DC output voltage. A controller generates a switching control signal for controlling the state of said switch. A protection circuit is connected to the controller for protecting the switched power supply from damage resulting when a reverse battery connection is made. The circuit also includes a controller for controlling the pulse-width of the control signals input to the switch. A fan may be provided on the housing which is selectively enabled to move cooling air over the switched power supply only when a detected temperature exceeds a threshold level. The controller may be disabled when an ambient temperature exceeds a threshold level. An optical coupler is utilized in a voltage feedback circuit. The voltage feedback circuit is compared to a current level to control the pulse-width of the pulse signal supplied to the switch. An overvoltage protection circuit is connected to the controller for protecting the switched power supply from damage resulting from an overvoltage condition.
