LLC resonant converters have emerged as the preferred topology for an intermediate 48 V to 12 V conversion due to their high efficiency, high power density and good dynamic response. The outstanding performance resulting from the combination of this topology with GaN transistors has been demonstrated in the past. This article presents how the newest generation of GaN devices, such as those from EPC, continues to push the envelope even further.

Power-conversion technologies are experiencing the first tectonic shift since the move from bipolar to MOS. That shift, of course, is due to the viral adoption of wide-bandgap power devices. At this point, GaN is more than a specialty technology; it is a broad-scale replacement for silicon MOSFETs in applications ranging from 30 V up to 650 V — a multibillion-dollar market.

Growing computational power and miniaturization of electronics in computing and data centers is increasingly putting pressure on 48-V power delivery and conversion systems. High-efficiency and high-power–density converters enable a reduction in power losses at the system level while allowing smaller form factors. In this context, LLC resonant topologies combined with GaN technology succeed to deliver outstanding performance, as it has been demonstrated with multiple examples. This article will show the key design parameters and components to achieve beyond 4 kW/in3 of power density in a 48-V to 12-V LLC converter using eGaN^® FETs.

Automotive 48 V/12 V converters are essential in modern hybrid electric vehicles, as the energy is exchanged between the 48 V and 12 V buses. This two-voltage system accommodates legacy 12 V systems and provides higher power for 48V to loads such as vacuum and water pumps, electric super chargers, steering, and audio systems. Among all the requirements for the 48 V/12 V converter, efficiency, power density, size and cost are on the top of the list. This article addresses these design criteria by employing the GaN ePower™ Stage, EPC23101, and compares it with a previous design using discrete EPC2206 devices.

Demonstrating the design of a bi-directional DC-DC converter for automotive 48 V power distribution, showing how GaN technology is a powerful enabler for efficient electrification. The trend towards increasing electrification in the automotive industry enables car makers both to deliver new innovations to market cost-effectively and to meet increasingly stringent emissions legislation. Raising the vehicle’s main bus voltage to 48 V helps meet the demands of power-hungry systems such as the start-stop motor/generator of a mild hybrid vehicle, as well as loads such as electric power steering, electric supercharging, and vacuum and water pumps.
