3300V IGBT module reports telemetry data for HV rail and power
Power Integrations introduced a single-channel gate driver for 190 x 140mm IHM and IHV IGBT modules up to 3300V at PCIM Europe. The 1SP0635V2A0D combines the company’s Scale-2 switching performance and protection features with a configurable isolated serial output interface. The modules provide comprehensive telemetry reporting for an accurate lifetime estimation and use multiple sensing circuits including thermal and device and bus condition information to simplify system design and enhance observability, control and reliability, said PI. The modules are for a wide range of application areas, for example in rail traction inverters, power grid and medium-voltage drives.
Telemetric data available from the 1SP0635V2A0D gate driver includes temperature measurement, which simplifies thermal management and eliminates the need for external temperature sensors. DC link voltage measurement is also incorporated, minimising 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 fibre 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.
The serial status output protocol incorporates critical real-time measurements to provide visibility on operational verification and the inverter’s health, reliability and efficiency. Engineers may adapt monitoring and control systems to the PI protocol or request custom adjustments by PI engineers, added the company.
The 1SP0635V2A0D gate drivers are available for sampling now.
