CPES researchers create first LLC converter meeting iNEMI requirements
Jun 30, 2016
This is an 800W 400V/12V LLC Converter, operating at 1MHz with GaN devices. It achieves a peak efficiency of 97.6%, which is the highest efficiency demonstrated at such high switching frequency. This converter employs a novel matrix transformer structure which integrates 4 transformers into 1 magnetic core. With those techniques, the converter achieves a power density of 900W/in3 and satisfies the quarter-brick footprint requirement. This is the first prototype meeting iNEMI’s requirement for the DC/DC converter of the future datacenter architecture.
