The Control Electronics is a real-time data acquisition and control system based on Atmel’s AVR microcontroller. The Control Electronics will be embedded into Rantec’s 3U power supply to monitor and report power supply data [1]. The power supply data monitored includes power supply output voltages, input voltage, DC bus voltage, and temperature.

The microcontroller continuously monitors DC voltages through seven I2C compatible analog-to-digital converters via a custom Two-Wire interface. An analog temperature sensor measures power supply data and feeds it as an analog voltage to the microcontroller’s built-in analog to digital interface. The microcontroller stores the acquired power supply data into a buffer for easy processing and to maximize its performance.

The Control Electronics reports the power supply data to an external Two-Wire master device via the microcontroller’s built-in Two-Wire interface, configured as slave.

This project describes the development and implementation of the Control Electronics data acquisition and control system.
