Single-Channel Plug-and-Play Driver with Master/Slave Operation, Drives IGBTs from 1200V to 3300V with On-board DC/DC Converter


Product Details

1SP0635 SCALE-2 Plug-and-Play drivers safely and reliably drive 130 x 140 mm and 190 x 140 mm high-voltage and high-power IGBT modules ranging from 1200 V to 3300 V. They are optimised for use in high-reliability applications in the rail industry.  

The drivers operate in a master/slave configuraion that allows the safe operation of parallel-connected IGBT modules. The master (1SP0635V or 1SP0635S) can be used as a stand-alone driver without slave to drive a single IGBT module or it can be used with up to three slaves (1SP0635D) to drive up to four parallel-connected IGBT modules. 

The master drive is equipped with a fiber-optic interface and global fault management. In master/slave configurations, the slaves are connected to the master by a bus cable which distributes the common command signal and the secondary-side supply voltages from the DC/DC converter. 

1SP0635 drivers are based on Power Integrations' highly-integrated SCALE-2 chipset. Therefore the single-channel drivers are high-performance, complete and extremely compact. The SCALE-2 chipset also reduces the component count by up to 80% compared to conventional solutions, thus significantly increasing reliability and reducing costs.

The drivers are equipped with Dynamic Advanced Active Clamping (DA2C), short-circuit protection, built-in DC/DC converters, regulated turn-on gate driving voltage and supply-voltage monitoring. 

Perfectly-matched drivers are available for all mechanically-compatible IGBT modules. Plug-and-play configuration allows immediate operation after mounting, so the user needs to invest no time and effort in designing or adjusting the driver for a specific application.

Fiber-Optic Interface Options
Fiber-optic links are used to provide electrical insulation for the command and status-feedback signals. Two versions of fiber-optic interfaces are available: 

  • 1SP0635V, equipped with Versatile links
  • 1SP0635S, equipped with ST links
