This paper proposes a digital nonlinear-carrier control (DNLC) power factor correction (PFC) technique. Considering that the total harmonic distortion (THD) of input currents in discontinuous conduction mode (DCM) is higher than in continuous conduction mode (CCM), the controller gives different compensation in CCM and DCM. The power factor (PF) and THD are demonstrated experimentally by field-programmable gate array (FPGA) and a 100 W boost PFC converter. The experimental results are shown for high PF of 0.982 and minimum of 7 % THD.
