3300 W 54 V bi-directional phase-shift full-bridge with 600 V

CoolMOS™ CFD7 and XMC™

Background and system description

The estimated overall distribution of losses of the converter along the load proves the transformer and other

magnetics as the main sources of loss (Figure 6). The semiconductors, both 600 V CoolMOS™ CFD7 and 150 V

OptiMOS™ 5, are best-in-class performance parts and exhibit a good balance of switching to conduction loss.

As highlighted by Figure 6, the great performance of the semiconductors makes the magnetic loss contribution

the major percentage in terms of losses in most of the working conditions of the converter.

CoolMOS™ CFD7

IPL60R075CFD7 stands for the 75 mΩ 600 V CoolMOS™ CFD7 in ThinPAK package, the latest and best-

performing fast body diode device from Infineon.

IPL60R075CFD7 brings a low loss contribution along all load ranges and exhibits a good balance of conduction

to switching losses at the 50 percent load point, becoming the right device and RDS(on) class when optimizing for

high peak efficiency at that point (Figure 7).
