Novel: High Efficiency Full-Bridge Rectifier Reference Design
TIDA-00858 implements a high efficiency novel approach to Full Bridge Rectifier. This TI Design replaces diodes with four N-Channel MOSFETs: combined with LM74670-Q1 Smart Diode Controllers in a Full Bridge Rectifier configuration. The LM74670-Q1 solution is highly effective zero IQ replacement of lossy diodes. This design can produce a rectified DC voltage without diode forward voltage drop for AC input voltage up to 45V. This LM74670-Q1 solution based full bridge rectifier can handle AC input of 300Hz frequency and up to 100A output current with less thermal management compared to schottky diode rectifier.
Supports AC input voltage up to 45VFast Response to Dynamic Current Reversal: More efficienty solution for high current rectifiersSupports AC input frequency up to 300HzZero IQ and smaller reverse leakage current compared to diodes rectifier
