Abstract
The operation of a high voltage gain boost dc-dc converter is investigated in this paper. This investigation consists of the calculation the critical inductance between continuous conduction mode (CCM), discontinuous conduction mode (DCM), complete inductor supply mode (CISM) and incomplete inductor supply mode (IISM). Then, the switches peak current is calculated in DCM and CCM. Moreover, the effect of the electrical parameters in the peak current of power switches is investigated and a method to minimize the output voltage ripple (OVR) by considering minimum switching current stress and size of filter is proposed. Finally, in order to verify the presented theoretical issues, the simulation results in EMTDC/PSCAD software program are used.
