EPC9163 KIT – 2 kW 48 V/12 V Bi-directional
Power Module Evaluation Board
The EPC9163 evaluation power module is a 2 kW, two-phase 48 V to/from 12 V bidirectional converter that
operates at high efficiency in a very small footprint. The design of this demonstration board is scalable;
that is, two converters can be paralleled to achieve 4 kW or three converters can be paralleled to achieve 6
kW. The board features eight EPC2218 100 V
eGaN® FETs and is controlled by a module (EPC9528) that includes the Microchip
dsPIC33CK256MP503 16-bit digital controller.
The fast-switching speed and low losses of the eGaN FETs allow the converter to operate at 500 kHz which
significantly reduces the size of the solution. The high switching frequency capability allows the use of
the extremely small IHTH-1125KZ-5A Vishay inductor in this design.
