SCALE-2+

The SCALE™-2+ chip set is Power Integrations’ most recent innovation within its SCALE™ family. New SCALE™-2+ technology enables soft shutdown (SSD) by 2SC0106T and advanced active clamping (A2C) or dynamic advanced active clamping (DA2C) by 2SC0115T.

Features:

  • implemented in all existing popular gate driver cores, delivering upwards compatible, lead-free versions with improved EMC performance. In the version 2SC0106T2A1 and 2SC0108T soft shut down (SSD) can get activated.
  • available in gate drivers with IGBT blocking voltages from 600V up to 4.5kV.

SCALE-2+ Benefits:

  • Very fast >10ns
  • Very low Jitter 1n
  • Low couple capacity
  • High di/dt ruggedness
  • Integrated secondary side voltage controller
  • +15V gate-Emitter clamping
  • Lower IGBT Short Circuit energy
  • Programmable full bride or direct mode
  • Common failure output
  • Under voltage lock off primary side
  • Under voltage lock off secondary side for positive and negative supply voltage
  • Embedded DC/DC controller with DC/DC soft starter
  • 3,3V to 15V PWM input
  • Reinforced galvanic isolation according to IEC60664-1

Applications:

  • Servo Drives and GP Drives
  • UPS and Power Supplies
  • Medium Voltage Drives
  • Statcom; Voltage source Inverters
  • Commercial and agriculture vehicles; electric vehicles)
  • Photo Voltaic equipment
  • Wind turbines
  • Traction Auxiliary Inverters
  • SiC Mosfet systems
  • High Frequency applications (x-ray, MR, Plasma cutting, welding, inductive heating electronic transformers)
