| Abstract | This work presents a new version of a microprocessor based high frequency switching mode power supply. The system, that is designed to be used in computer systems as main and standby power supply, is controlled by a microprocessor card constructed around the MC6802 microprocessor. The system is composed of two controllable converters and two uncontrollable converters: - A step down chopper used as a power supply of the standby battery. - A single phase voltage source inverter used to supply the high frequency transformer. - A single phase diode bridge rectifier used as the input of the power supply. - A centre taped two way rectifier fed to the output of the high frequency transformer. The system possesses, in addition to a high quality output voltage regulation, some protection from over-voltages and over-current. |
