Abstract
A satellite receiver which is capable of being connected to different antenna assemblies which require different operating voltages, includes a switch mode power supply which supplies the different operating voltages. A microprocessor controls the duty cycle of the switch mode power supply to produce the different operating voltages in accordance with the required duty cycle. A memory stores values which define different duty cycles for each of the operating voltages and provides the values to the microprocessor.
