IMS Evaluation System Ogles 3-kW+ Applications

GaN Systems’ Insulated Metal Substrate (IMS) Evaluation Platform is described as a flexible, low cost, high power development platform for high-efficiency power systems with 3kW or higher applications. The IMS Evaluation Platform, in combination with GaNPX packaging technology and smart design techniques, enables power engineers to quickly take full advantage of GaN power transistors in designing smaller, lighter, lower cost, and more efficient power systems for data center, automotive, and energy storage system applications.

 

This platform consists of a motherboard (GSP65MB-EVB) and two IMS evaluation modules in half bridge and full bridge variants. The modules can be configured as a half-bridge (single IMS module) or a full bridge (two IMS modules) on the high-power motherboard. IMS evaluation modules are available in two power levels: 3kW (GSP65R25HB-EVB) and 6kW (GSP65R13HB-EVB). The IMS evaluation module includes GaN E-HEMTs, gate drivers, isolated DC/DC supply, DC bus decoupling capacitors, and a heatsink to form a fully functional half bridge power stage.

Features include:

  • Low Thermal Resistance & Optimized Layout: The IMS platform enhances the thermal and electrical performance benefits of GaNPX® E-HEMTs. The drive board is tightly coupled with the IMS board to minimize power commutation and gate driver loops to optimize performance.
  • More Flexibility: The platform is very flexible, enabling twelve different configurations, architectures, and operating modes. IMS evaluation modules can be used independently as a high-power GaN intelligent power module with developers’ own system boards for in-system prototyping.
  • Greater Power Density: Using IMS boards for transistor mounting takes advantage of the vertical space available in larger power applications. The optimized driver board not only minimizes both power and gate driver loops, it also increases the power density of the electronics.
