Abstract:
advancement and stringent requirements on various scientific
experiments. Any industrial plant or scientific experiment mainly
consists of actuators, sensors, electronics, power supplies, and software.
The power supply requirement of any load is dynamic in terms of
voltage amplitude, current consumption, predefined temporal profile,
interlock supports for fail-safe operation. The programmable settings
of various parameters of power supply and real-time monitoring
of outputs is necessary for automation and remote operation of the
application. In general, the analog power supply (APS) has manual
control of output and does not support computer interfacing feature.
The digital controller or processor offers computer interfacing facility
with signal acquisition using analog to digital converter (ADC),
signal processing using processor and control task using digital to
analog converter (DAC). The digital power supplies usually have
readily available computer interfacing port for automation. This paper
mainly focuses on the design, development, and automation of analog
(DC–DC converter) and digital power supply. The design of inhouse
field programmable gate array (FPGA) based add-on board
for automation of multichannel APS is discussed in detail. Finally,
development of LabVIEW-based graphical user interface (GUI) for
setting and monitoring of various parameters of the system is discussed.
The demonstration of designed hardware and software is checked
for one of the power supply sections of optoelectronics laboratory. The developed work is upgradable to multiple simultaneous channels
for monitoring and control. We believe that the developed work will be
useful for many industrial and research applications.
