Digital Inrush Controller
●Introduction:
■This application note describes a Digital Inrush Controller that combines IXYS digital power control technology and Zilog’s 8-bit Z8F3281 MCU capabilities to illustrate a unique approach to control inrush current in AC-DC rectifiers or AC-DC converters. There are two objectives: first, to illustrate advantages of digital control that overcomes many of the disadvantages of the used right now technology, and second, to raise interests in digital control of the high power converters, potentially stimulating development of its next generation. IXYS digital control would allow the integration of control circuits and power devices on the same integrated circuit or semiconductor chip, according to the so-called “smart power” concept, which has a significant role in switched-mode power supply (SMPS) for achieving higher power densities.
■Digital control allows distinctive solutions to control inrush current in typical AC-DC rectifier with capacitive load by limiting capacitor pre-charge current to a predetermined value at each half sine-wave cycle. Capacitor charge is spread over a number of cycles until capacitor is charged proportion of peak value of AC voltage source. Capacitor is charged according to time-dependent pulse train. The pulses are designed in a way to provide substantially equal voltage increment applied to capacitor to keep peak of charging current about the same value at each cycle. Number of cycles depends on capacitor value and charge current. For a given capacitor value which is selected depending on desired ripples amplitude, the charge current is a function of number of pulses and its timing position with respect to rectified sine wave. Detailed algorithm of creating pulse train for Digital Inrush Control is described in the Principles of Operation section.
■IXYS Digital Inrush Controller features programmable overload protection and “Power Good” status signal. It is not sensitive to power outage, brownout and ambient temperature variations. It can operate with input voltage range from 80V to 240V AC and load current up to 3A. Entire operation process and essential values are fully programmable. The controller may be programmed to 50 Hz, 60 Hz or any other line input frequency operation.
■This Digital Inrush Controller is valuable for high power loads with tens of Amperes of current in normal mode operation. It allows users to optimize the performance, maximize the efficiency across the load range and reduce the design time to market. IXYS power components allow handle pre-charge of load capacitors at this values while limit inrush current to controlled values.
