  • Abstract
    A method of establishing the boundary between discontinuous conduction mode (DCM) and continuous conduction mode (CCM) operation of fourth-order PWM power converters (Cuk, Sepic, Zeta etc.) with parasitic elements is presented. The boundary between DCM and CCM, considered to be the critical load resistance Rcrit, is found as the positive root of a second-degree equation with unknown Rcrit
