A high efficiency, 3 kW capable, 2-phase, 3-level Converter using paralleled eGaN FETs

A high efficiency, 3 kW capable, 2-phase, 3-level Converter using paralleled eGaN FETs

As the revolution of renewable energy as well as transportation electrification progresses, the need for residential energy storage systems is increasing. A high efficiency DC-to-DC converter is usually required to exchange energy generated from renewable sources, such as solar panels, with a battery. The fast-switching speed and low RDS(on) of gallium nitride (GaN) FETs can help save energy by reducing power consumption inside the DC-to-DC converter. This article shows how to design a high efficiency 100 – 250 V to 40 - 60 V DC-to-DC converter.

Efficient Power Conversion (EPC) and BrightLoop Converters Combine Design Expertise to Produce Smaller, Lighter Converters for Performance eMotorsport Vehicles

Efficient Power Conversion (EPC) and BrightLoop Converters Combine Design Expertise to Produce Smaller, Lighter Converters for Performance eMotorsport Vehicles

EL SEGUNDO, Calif. — December 2020 — BrightLoop Converters has greatly reduced the size, cost and improved reliability of its latest BB SP DC-DC buck converters thanks to Efficient Power Conversion Corporation’s (EPC) EPC2029 enhancement-mode gallium nitride (eGaN®) FET transistors. By switching from silicon (Si) transistors to gallium nitride (GaN), BrightLoop was able to increase the switching frequency of their design from 200 kHz to 600 kHz, while keeping the same efficiency. This design change increased the power density of the solution by a factor of approximately two and this resulted in lower cost by enabling the implementation of a smaller enclosure.

EPC’s EPC2029 is an 80 V, 48 A eGaN® FET featuring a 1 mm ball pitch. The wider pitch allows for placement of additional and larger vias under the device to enable high current carrying capability despite the extremely small 2.6 mm x 4.6 mm footprint.
