BrightLoop leverages EPC’s GaN transistors for EV applications

BrightLoop Converters is teaming up with Efficient Power Conversion (EPC) to deliver the upcoming Value line of high-power DC-DC converters.

The Value product line is composed of two converters, M and L, delivering 6 kW/300 A and 12 kW/600 A, respectively. BrightLoop says the power converters have a smaller footprint and lower weight than equivalent converters currently available, and comply with market standards such as ECE R 10, ECE R 100 and LV 124. 

BrightLoop’s Value DC-DC converters can be used in 12 V, 24 V and 48 V architectures, and with 400 or 800 V, or more. They are available in single or dual output versions, and the output voltage can be set via CAN between 10 V and 54 V, allowing the removal of some vehicle components, such as the battery equalizer that would typically be used when there are several batteries in a system. Also, the converters offer a reversibility function that allows pre-charging the HV bus without the need for bulky resistors.

These features are made possible by the use of EPC’s EPC2029 enhancement-mode gallium nitride (eGaN) FETs. The EPC2029 is an 80 V, 48 A eGaN FET featuring a 1 mm ball pitch. The wider pitch allows for the placement of additional and larger vias under the device to enable high current carrying capability in a 2.6 mm x 4.6 mm footprint.
