At a Power-Factor-Correction (PFC) circuit, Why mostly using Continues Conduction Mode (CCM) for high power applications, ex. above 300 kW, and using Boundary Conduction Mode (BCM) or Discontinuous Conduction Mode (DCM) for low power applications?

    \$\begingroup\$ Mostly EMC related - CCM has the lowest peak inductor current is and considered the 'quietest' method. CRM and DCM have higher peak inductor currents. \$\endgroup\$ – Adam Lawrence Sep 17 at 16:10
