1SD312F2 drivers are based on Power Integrations sophisticated SCALE-1 driver chipset. Devices are fully equipped with protection functions including: Vce-monitoring for short-circuit protection; operation inhibit after fault; and supply undervoltage shut down.
The 1SD312F2 series drivers feature an active clamping function, offering rugged and high-performance protection for costly IGBTs.
Operating the gates with a bipolar control voltage (typically ±15 V) allows the IGBT modules to be driven reliably with a high level of immunity to interference.
Fiber-optic Interface Options
Fiber-optic links (Versatile Links) are used to provide electrical isolation of the command and status-feedback signals. For details, please check the product documentation.
Power supply and electrical insulation
In contrast to the other SCALE-1 plug-and-play products, 1SD312F2 family drivers are modular with the driver card and power supply (DC/DC converter) provided as two separate units.
Because of this modular concept, any driver unit that has been developed to match a specific IGBT module can be used for any required insulation specifications. Only the power supply must be chosen or adjusted for the specific application.
Therefore, 3.3 to 6.5 kV IGBTs drivers can be implemented in 2-level, 3-level and multi-level inverter topologies.
The driver unit is mounted directly onto the IGBT module using three screws. The power supply is attached separately, but close to the IGBT.
