•PFC

• - Various topologies to power such as NPC, TNPC, Vienna, etc.,
• - Normally 100kHz of switching frequency
• - CCM switching is normal
• - Low VCE(sat) > E_on ≈ E_off

•CLLLC

• - Normally 100kHz~150kHz of switching frequency
• - ZVS and turn off loss are dominant
• - Short circuit capability by di/dt, dv/dt at output short-circuit condition
