Module gate driver uses SCALE-2 switching performance and protection features
Power Integrations has released a single-channel, plug-and-play gate driver for 190 x 140mm IHM and IHV IGBT modules up to 3300V. 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.
The company claimed that the serial status output protocol incorporates critical real-time measurements, facilitating advanced operational verification and dramatically increasing overall visibility of the inverter’s health, reliability and efficiency. It said engineers may adapt monitoring and control systems to the PI standard plug-and-play protocol or request custom adjustments by PI engineers during their project’s development phase.
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, and claimed to minimise external circuitry, reduce 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 fibre-optic interface to ensure that switching commands are received correctly. 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.
The 1SP0635V2A0D gate drivers are available for sampling now.
