EL SEGUNDO, Calif. – Efficient Power Conversion Corp. (EPC) in El Segundo, Calif., is introducing the EPC9163 two-kilowatt and two-phase 48- and 12-volt DC-DC converter demonstration board for efficient, small, and fast bidirectional converters in mild-hybrid cars and battery backup units.
These power electronics devices use gallium nitride field effect transistors (GaN FETs), and operate with 96.5 percent efficiency in a small footprint.
The design is scalable, in that its two converters can be paralleled to achieve 4 kilowatts, or three converters can be paralleled to achieve 6 kilowatts. The board features eight EPC2218 100-volt eGaN FETs and is controlled by a module that includes the Microchip dsPIC33CK256MP503 16-bit digital controller.
The fast-switching and low losses of the EPC9163 DC-DC converter demonstration board enables the converter to operate at 500 kHz to reduce its size. The high switching frequency capability enables the use of the extremely small IHTH-1125KZ-5A Vishay inductor in this design.
