Description
- TIDA-00858, Novel, High Efficiency Full-Bridge Rectifier Reference Design. The TIDA-00858 implements a high efficiency novel approach to Full Bridge Rectifier. This 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 loss 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
