In higher power applications to utilize the full line power and reduce line current harmonics PFC

Pre-regulators are generally required. In these high power applications interleaving PFC stages can

reduce inductor volume and reduce input and output capacitor ripple current. This results in smaller overall

magnetic volume and filter capacitor volume increasing the converters overall power density. This is made

possible through distributing the power over two interleaved boost converters and the inductor ripple

current cancellation that occurs with interleaving, reference [5]. This application note will review the design

of a 300W two-phase interleaved power factor corrected (PFC) pre-regulator. T
