GaN power module evaluation kits target high-power applications

GaN Systems has introduced four new integrated GaN power module evaluation kits that make it easy to evaluate gallium nitride (GaN) power devices for high-power applications. These include traction inverters, industrial motors, energy storage systems, PV inverters, and a variety of lower power board and brick power supplies.

The four evaluation kits include: a 100-V driver GaN DC/DC power stage module; 650 V, 150 A half-bridge intelligent power module (IPM); 650 V, 150 A full-bridge module and driver, and 650 V, 300 A 3-phase module and driver.

Here’s what you get in each kit.

• 100-V driver GaN integrated DC/DC power stage module provides high power density and efficiency for DC/DC topologies. The integrated module features a 7-mΩ half-bridge power stage, ultra-low R-theta, high output power, and dual pulse width modulation (PWM) input with ultra-low dead time. Applications include 48-V step down converters, high-performance Class D audio systems, CPU/GPU/DDR, 48-V to 12-V bricks and board forward converter, ZVS, and buck/boost topologies. The module is also available mounted on an evaluation board for easy testing, said GaN Systems.
• 650-V, 150-A half-bridge IPM is designed with an industry-standard low-profile case with press-fit pins. The module provides an integrated gate drive, 10 mΩ R_DS(on) , superior thermal performance, and ultra-small form factor (82 x 38 mm). Designed for high-efficiency, high-frequency switching applications, this kit is suited for PV inverters, energy storage systems (ESS), uninterruptible power supplies (UPSes), and variable frequency drives (VFDs).
• 650-V, 150-A full-bridge module and driver offers the benefits of lower losses and cooler operating temperatures, high efficiency, increased power density, and reduced volume and weight, said GaN Systems, and an external optimized and isolated gate driver board is available for easy evaluation. Applications include PV Inverters, ESS, UPS, VFD, automotive traction inverters, and on-board chargers (OBC).
• 650-V, 300-A 3-phase GaN power module and driver is designed with an industry-standard form factor with high performance and high-power density for automotive and industrial markets. This module provides a high-thermal-conductivity base plate, press-fit pins for ease of assembly, and ZTA substrates for higher reliability. It also provides an external optimized and isolated gate driver board for easy evaluation of the module. Applications include high efficiency 75-kW traction inverter drives and motor drives.
