The Popular Technologies of Power Conversion ► Zero-Voltage-Switching Phase-Shifted Full-Bridge Converter • Reduced switching losses – zero-voltage switching • Fixed frequency • Suit for isolated power converter ► Resonant Converter (FSL-LLC) • Low switching losses Transistor turn-on occurs at zero voltage - Zero-voltage switching Transistor turn-off occurs at zero current – Zero-current switching • Reduce converter-generated EMI • Variable switching frequency which range can be very large • Not good for input voltage variation • Not good for filter design ► Multiple-Phase DC/DC Buck Converter • Input/output ripple cancellation • Less input/output capacitance needed • Reduce power dissipation and improve efficiency ► Interleaved PFC (Power Factor Correction) • Transition mode and continuous current mode • Inductor volume reduced • The ripple-current cancellation at the input of the power converter, reduced conductive loses due to current ripple • Alleviating electrical overstress on capacitor • Redundant phases can be shut down for efficient operation Freescale, the Freescale logo, AltiVec, C-5, CodeTEST, CodeWarrior, ColdFire, C-Ware, mobileGT, PowerQUICC, StarCore, and Symphony are trademarks of Freescale Semiconductor, Inc., Reg.
