Hot Swapping Capability Analysis of Multi Modular Input-Series Output-series DC-DC Converter


Converters either supplying power to vital loads (communication centers, hospitals, protection devices etc.) or connected with the generation systems especially renewable types, are such sophisticated units that their failure can lead to financial as well as life losses. This paper focus on the capability of the multi-modular DC-DC converter to successfully replace the faulty module of the converter with the healthy one without the load being disturbed (Hot-swap). Using modular converters has been proved a better substitute in terms of cost-efficiency and reliability while improving the overall efficiency of the converter. The proposed model is simulated in Matlab and the results validate the statement during the hot-plug of any module without disturbing voltages at load terminals.
