摘      要：Multi-converter system is mainly used in advanced automotive *** converters and inverters are taking part in automotive systems to provide different voltage levels in a multi-converter *** involves constant voltage load(CVL),constant power load(CPL)and other *** CPL in such systems offers negative impedance characteristic and it creates a destabilizing effect on the main *** effect of destabilization can be reduced by increasing the CVL or inserting parasitic *** have been made by authors to improve the stability by using parasitics of different components such as switch,diode and *** of insertion of parasitics including the series equivalent resistance of the filter capacitor and variation in CVL on the performance of main converter is mathematically analyzed and conflicting behavior between system stability and efficiency is *** optimum solution between these two functions is obtained by using multi-objective decision making(MODM)by varying parasitics of different components and *** attempt has been made to demonstrate the effect of CVL load and the parasitics on the stability and efficiency of the main converter,experimentally.
