Analysis of operational modes of step-up dc-dc converter with high voltage gain and calculation of output voltage ripple
In this paper, the operational of step-up dc-dc converter with high voltage efficiency is analyzed. The amount of critical inductance is calculated between continuous conduction mode (CCM) and discontinuous conduction mode (DCM).In addition, the amount of critical inductance is computed between complete inductor supply mode (CISM) and incomplete inductor supply mode (IISM). Moreover, the output voltage ripple (OVR) is analyzed in definite limitation of input voltage and output load resistance. The maximum output voltage ripple (MOVR) is calculated based on computed converter parameters and ultimately for obtaining minimum ripple of maximum output voltage, the amount of minimum inductance should be computed. The simulation result in software PSCAD/EMTDC is also presented for reconfirming and proving the obtained mathematical theories.
