Littelfuse Inc., a manufacturer of circuit protection, power control and sensing technologies, has announced 
Source: Littelfuse Inc.the Gate Drive Evaluation Platform (GDEV). The new evaluation platform helps designers evaluate silicon carbide (SiC) MOSFETs, SiC Schottky diodes, and other peripheral components like gate driver circuitry, so that they can better understand how SiC technologies will behave in converter applications under continuous operating conditions.
The GDEV offers quick connect header pin terminals that allow for rapid and consistent comparison of different gate drive circuits, unlike most other SiC evaluation platforms. The GDEV supports an 800 V DC link input voltage and up to 200 kHz switching frequency.
Typical markets and applications for the GDEV include:
- Automotive EC/HEV charging stations
- Industrial power supplies
- Datacenter servers
- Telecom base stations
- Solar/wind power inverters
The GDEV from Littelfuse enables users to:
- Evaluate continuous operation of SiC power MOSFETs and diodes under rated voltage and rated current, delivering real power to the load.
- Analyze system-level impacts associated with SiC-based designs including efficiency improvements, EMI emissions and passive components (size, weight, cost).
- Compare the performance of different gate driver solutions under well-defined and optimized test conditions.
- Test gate driving circuits under continuous working conditions to evaluate gate driver thermal performance and EMI immunity.
