GaN Systems adds integrated power module evaluation kits
GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) has announced the availability of four new integrated power module evaluation kits, designed to be easy to use and evaluate performance in high-power applications such as traction inverters, industrial motors, energy storage systems, photovoltaic (PV) inverters, and a variety of lower-power board and brick power supplies:
- The 100V Driver GaN DC/DC Power Stage Module provides high power density and efficiency for DC/DC topologies. The integrated module features a 7mΩ half-bridge power stage, ultra-low R-theta, high output power, and dual PWM (pulse width modulation) input with ultra-low dead time. Applications include 48V step-down converters, high-performance Class D audio systems, CPU/GPU/DDR, 48V-to-12V bricks and board-forward converter, ZVS, and buck/boost topologies. The module is also available mounted on an evaluation board for easy testing.
- The 650V 150A Half-Bridge IPM (intelligent power module) is designed with an industry-standard low-profile case with press-fit pins. The module provides an integrated gate drive, 10mΩ on-resistance (RDS(on)), superior thermal performance, and ultra-small system form factor (82mm x 38mm). Designed for high-efficiency, high-frequency switching applications, the kit is suitable for PV inverters, energy storage systems (ESS), uninterruptible power supplies (UPS), and variable frequency drives (VFD).
- The 650V 150A Full-Bridge Module and Driver features are similar to the 650V 150A Half-Bridge IPM and offers the benefits of lower losses and cooler operating temperatures, high efficiency, increased power density, and reduced volume and weight. External optimized and isolated gate driver board is available for easy evaluation of the module. Applications include PV inverters, ESS, UPS, VFD, automotive traction inverters, and on-board chargers (OBCs).
- The 650V 300A 3-Phase GaN Module and Driver is designed with an industry-standard form factor, featuring high performance and high power density to meet the requirements of automotive and industrial markets. The module provides a high-thermal-conductivity base plate, press-fit pins for ease of assembly, and ZTA substrates for superior reliability. An external optimized and isolated gate driver board is available for easy evaluation of the module. Applications include high-efficiency 75kW traction inverter drives and motor drives.
GaN Systems says that the evaluation kits are popular with design engineers, and that the growing multitude of design resources make GaN easy to incorporate and take advantage of the benefits of high efficiency and smaller size and weight.
