Infineon EVAL_3K3W_BIDI_PSFB DC-DC Converter for Industrial, Power Supplies

This evaluation board introduces a highly efficient complete Infineon system solution for a 3300W bi-directional DC-DC converter targeting telecom, battery formation power and industrial robotics applications.
Infineon’s 600V CoolMOS™ CFD7 superjunction MOSFET in ThinPAK package is the most recent and best performance fast body diode device. Combined with a low parasitic package and an optimized layout, it achieves great performance with minimum stress. The innovative cooling concept presented in this board enables its remarkable performance.
This board achieves 98% efficiency in buck mode and 97% in boost mode. The attained power density is in the range of 4.34W/cm³ (71.19W/in³), which is enabled by the use of SMD packages and the innovative stacked magnetic construction.

When combined with the latest technologies from Infineon, this DC-DC converter proves the feasibility and high efficiency of PSFB designs at the level of fully resonant topologies.
The EVAL_3K3W_BIDI_PSFB shows as well that the PSFB topology can be used as a bi-directional DC-DC stage without changes in the standard design or construction of a traditional and well known topology. This is achieved thanks to innovations in control techniques powered by digital control and XMC™ microcontrollers.
