Development of a 12 V/48 V bidirectional DC/DC converter for mild hybrid applications using PCB embedded MOSFET half-bridge pre-packages
- This paper presents design, fabrication, and analysis of a PCB embedded half-bridge. Here, a pre-package that contains a 100 V / 100 A MOSFET half bridge is fabricated and embedded into a converter level power PCB, allowing for two routing layers on top of the semiconductors. This enables to minimize the commutation loop inductance by placing a decoupling capacitor directly on top of the switches. Experimentally a parasitic inductance of 1.4 nH is deducted from the ringing frequency in switching experiments. The second design goal is an optimized thermal performance. Both, simulation with ANSYS Icepak and experiments indicate a value of 1.77 K/W. Based on the results, a 12 V / 48 V bidirectional converter was implemented and operated with a maximum power of 620 W.
