In this paper an approach of computer design, simulation and implementation of multi switched mode power supplies (SMPS) controlled by one microprocessor is investigated. The design of three switch mode power supplies based on flyback DC-DC converters with different power 20,24 and 6 Watt and output voltages rated +5V,+12V/ and -12V are achieved. The design power stage is based on the bipolar as the main switching device with protection network used to ensure safe operation. The microprocessor and its supervisory board are used with slight software program to control the output of the multi switched mode power supplies (SMPS ) even though they have different switching frequency, output voltage, output power. The system performance is simulated and examined under many desired conditions. From the obtained result it was found that, it is efficiently and easily to use one microprocessor to control of multi switched mode power supplies reducing the complexity of the system
