IR1110 SOFT START CONTROLLER

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.
