Abstract :
This paper presents efficiency comparison of quadratic boost converter in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). Analytical expression for the DC component and RMS component of currents in CCM and DCM is derived. Total losses incurred in quadratic boost converter are calculated. Discontinuous conduction modes in three cases are discussed. The simulation result in software MATLAB/SIMULINK is presented for validating the results obtained by mathematical theories.
