Keysight Technologies, Inc. announced a new dynamic power device analyzer with double-pulse tester (PD1500A) to deliver reliable, repeatable measurements of wide-bandgap (WBG) semiconductors, while ensuring the safety of the measurement hardware and the professionals performing the tests.
According to Keysight Technologies, global growth of the electric vehicle market is driving strong demand for small, high power, efficient electric power systems. As the industry turns to WBG semiconductor technology for mission critical applications like renewable energy and EVs, many power converter designers are hesitant to adopt this new technology due to potential reliability and repeatability risks in characterizing a new generation of semiconductors including IGBTs, SiC and GaN.
Fully characterizing a SiC or GaN device requires static and dynamic measurements. Keysight's B1505A and B1506A Power Device Analyzers deliver these static measurements and, with the addition of the new PD1500A, now also provides the flexibility needed to address a variety of dynamic measurements. This functionality is key since the standards for WBG devices, established by the Joint Electron Device Engineering Council (JEDEC), continue to evolve. JEDEC is a semiconductor trade and engineering standardization organization.
Keysight's PD1500A is designed to be modular, allowing many device types to be tested and different characterization tests to be performed at a variety of power levels. The initial system provides complete double-pulse test characterization and parameter extraction for Si and SiC power semiconductors with ratings up to 1.2kV and 200A. Additional modules will be added to the PD1500A in the future to perform tests on devices requiring more current, such as GaN and power modules.
"To safely and consistently make the switch to innovative power devices, the automotive e-mobility ecosystem needs to evolve past using homegrown dynamic testing systems, which can be unreliable with non-warranted performance and characteristics," stated Siegfried Gross, vice president and general manager of Keysight’s Automotive and Energy Solutions Group.
"Keysight worked closely with semiconductor manufacturers, as well as designers in the energy and EV industries, to deliver a dynamic power device analyzer platform that includes the essential double-pulse test measurement capability to achieve repeatable, reliable and safe dynamic power device characterization," Gross added.
Keysight's new PD1500A Dynamic Power Device Analyzer with Double-Pulse Test Capability provides reliable, repeatable measurements of WBG semiconductors that enable customers to:
- lower costs and accelerate time to market by reducing design time and number of prototypes needed
- ensure a safe test environment
- document, support and maintain an off-the-shelf test solution, as well as maintain multiple test solutions across one or more sites
- quickly respond to reliability concerns with measurements that focus on ruggedness (e.g., short-circuit and avalanche)
- simplify and automate the testing processes
- improve device models used in design and simulation software (PD1000A)
