Power Integrations’ New 3300 V IGBT Module Gate Driver Reports Telemetry Data for Observability, Predictive Maintenance and Lifetime Modeling

Power Integrations announced a new, single-channel, plug-and-play gate driver for 190 mm x 140 mm IHM and IHV IGBT modules up to 3300 V. The 1SP0635V2A0D combines Power Integrations’ proven SCALE-2™ switching performance and protection features with a configurable isolated serial output interface, which augments driver programmability and provides comprehensive telemetry reporting for an accurate lifetime estimation. Multiple sensing circuits including thermal and device and bus condition information are incorporated, simplifying system design and enhancing observability, control and reliability. Application areas are rail traction inverters, power grid and medium-voltage drives.

Telemetric data available from the 1SP0635V2A0D gate driver includes accurate temperature measurement, which simplifies thermal management and eliminates the need for external temperature sensors. DC link voltage measurement is also incorporated, minimizing external circuitry, reducing system complexity and cost. Closed-loop gate voltage, gate status and short-circuit monitoring ensure that modules are operated within set limits, improving efficiency and avoiding catastrophic failures.

Other features include a status monitor for the fiber-optic interface to ensure that switching commands are received correctly. Similarly, gate monitoring ensures switching commands have been executed correctly and that the power module is in the appropriate operating condition. Short-circuit monitoring provides accurate control, directing the gate driver to respond appropriately in the event of a short circuit (more info, photo: Business Wire).
