IR1110

Overview

The IR1110 is a high performance analog IC designed to control ramp rate and voltage of the DC bus from either single or three phase AC line voltage input. It controls a SCR half bridge and provides robust ride through capability in event of transient loss of line, and DC bus regulation with eternal reference input.

  • Self-contained soft charging of DC bus capacitor
  • DC bus voltage regulation
  • 3-phase or 1-phase AC input
  • Applicable to 115/230/380/460/575V AC input
  • Drives SCR phase controlled half bridge
  • Programmable ramp rate
  • Protection against DC bus short circuit
  • Fast power dip ride through with automatic ramp back
  • Selectable shutdown on single phase loss
  • 1-phase and 3-phase loss fault output
