Description

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.

Features
  • Supports AC input voltage up to 45V
  • Fast Response to Dynamic Current Reversal: <5µsec
  • More efficienty solution for high current rectifiers
  • Supports AC input frequency up to 300Hz
  • Zero IQ and smaller reverse leakage current compared to diodes rectifier
