400V – 12V/500W High Frequency Resonant Converter Reference Design Using High Voltage GaN Devices

Overview

TopologyLLC Resonant Converter
Input voltage200-400 V
Output 15 V
IC revisionA

Description

The PMP20289 was built and tested to verify the performance of a high frequency (>400kHz nominal switching frequency) LLC series resonant converter (LLC-SRC) implemented with Texas Instrument’s high voltage GaN FETs under nominal (390V to 12V) voltage conversion. The digital controller UCD3138A is used along with the UCD7138 SR controller to optimize LLC-SRC efficiency. TI’s high voltage direct drive GaNFET LMG3410 is used to enable fast switching and be able to minimize dead-time between half-bridge switches. The test results show that 96.8% peak efficiency is achieved at 24A load and 96.3% efficiency is achieved at 42A full load with a switching frequency over 350kHz in a 390V to 12V conversion.
