Sensitron and EPC Collaborate to Introduce a High-Power Density 350 V Gallium Nitride (GaN) Half Bridge Intelligent Power Module (IPM) That is 60% Smaller Than Comparable Silicon Solutions and Lower C

Sensitron introduces the SPG025N035P1B GaN half-bridge module using the 350 V EPC2050 eGaN® FET from Efficient Power Conversion (EPC)

EL SEGUNDO, Calif.— May 2022, Reducing size and cost were key concerns of Sensitron when designing their latest generation GaN power modules. By replacing traditional silicon FETs with EPC’s 350 V, EPC2050 GaN FET, Sensitron was able to reduce the size of their solution by 60% while also improving the module’s already excellent junction-to-case thermal conduction. The SPG025N035P1B from Sensitron is a high-power density 350 V, 20 A GaN half bridge with an integrated gate drive, optimized for stray inductance and switching performance at 500 khz. Rated at 20 A, the module can be used to control over 3 kW. Sensitron’s proprietary topside cooling technology on this ultra-small, lightweight high power density package (1.10" x 0.70" x 0.14") allows for optimal thermal performance. The SPG025N035P1B was designed for commercial, industrial, and aerospace applications.

GaN vs. Silicon Smackdown

GaN vs. Silicon Smackdown

One way to tell when a new technology has passed the tipping point of adoption is by the voices advocating the status quo. The more conservative voices tend to cite older information that, given the fast change of trajectory that occurs at a tipping point, can lead to poor decisions for new designs. In the world of GaN power devices the tipping point occurred in the past two years when the rate of new GaN-based designs started to double year-on-year, and the legacy MOSFET designs started to face critical supply shortages due to their finely tuned, but less flexible supply chains. GaN devices, on the other hand, have remained in stock at most major distributors due to their relatively new and flexible supply chains utilizing older silicon foundries, but affording these foundries a new and vibrant future. In this article we will address some of the common misconceptions still showing up in articles and at conferences, usually presented by advocates of the status quo.

Multi-phase MHZ Converter with GaN

Multi-phase MHZ Converter with GaN

This article presents a two-phase DC/DC GaN converter with 120 VDC input operating at 6.7 MHz. 120 VDC is a standard voltage level in the secondary power system at the International Space Station (ISS). Using GaN FET’s high power density and ultra-fast switching, Tell-i’s newly developed SDK board uses two phases to exceed normal switching speeds. Supporting a standard 120-V bus voltage, as used in systems like the ISS, the multi-phase configuration allows interleaving converters to achieve effective switching at 3 MHz, 5 MHz, and an outstanding 6.87 MHz. Optimal and compact layout is achieved with the use of four EPC2019 GaN transistors and two LMG1210 gate drivers for small gate drive and power loops.

High Performance 1 kW per Phase 48 V/12 V Converter Using GaN ePower Stage

High Performance 1 kW per Phase 48 V/12 V Converter Using GaN ePower Stage

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.
