Reference Design: Digital Inrush Current Controller (IXRD1001)

The Digital Inrush Current Controller reference design combines IXYS’ Digital Power Control technology with the capabilities of Zilog’s 8-bit Z8F3281 microcontroller, a member of the Z8 Encore! XP F6482 Series of MCUs, to display a unique approach to control inrush current in AC–DC rectifiers or AC–DC converters.

 

The Digital Inrush Current Controller reference design offers the following features:
  • Input voltage range from 80V to 240V RMS
  • Steady load current up to 3A
  • Programmable overload protection
  • Power Good status signal
  • High endurance
  • Voltage ripples 15% at 2.5A load and output capacitance of 720μF
  • Option to expand bulk capacitor value using external capacitors

 

This reference design is valuable for high power loads with tens of amperes of current in Normal Mode of operation. It allows users to optimize performance, maximize efficiency across the load range, and reduce the design time to market. IXYS power components handle the pre-charge of load capacitors at these values while limiting inrush current to controlled values.

 

This Digital Inrush Current Controller reference design provides a basis for developing a variety of power management applications using Zilog's MCU with IXYS power devices, including the following applications:
  • High Power AC– DC Rectifier
  • High Power AC– DC PFC Converter
