资料介绍
PowerSeminar-2Interleaved PFC technology bring up low ripple and high efficiency

1
Proprietary Information

Presentation Outline
Introduction to Interleaved transition mode PFC
Comparison to single-channel CCM PFC Comparison to so-called “master/slave” architecture

Interleave technology benefit us.
Ripple cancellation to drive lower system cost Improved efficiency via enhanced phase management to drive higher system performance Continuous Transition Mode operation minimizes switching losses associated with MOSFET junction capacitors (result of DCM operation)

TI Interleave solution: UCC28060
Faster transient response via slew rate comparator “Fail Safe” OVP pin to provide additional system safety Implementation of current limiting drives lower system costs, improved reliability and higher efficiency
