Experimental reliability estimation of MPPT converter's in different operating modes

Failure rate as well as Reliability plays an important role in power electronic systems by which the number of system failures, repair costs, guarantee and etc are estimated. In this paper first, a boost Maximum Power Point Tracker (MPPT) converter is constructed in Discontinues Conduction Mode (DCM) and Continuous Conduction Mode (CCM). Then, reliability calculation is done based on MIL-HDBK-217F standard. Results have shown that the converter would have better performance from reliability point of view in CCM operating mode.
