The Utilizing Hall
Effect-Based Current Sensor ACS712 for TRUE RMS Current Measurement
in Power Electronic Systems
Đorđe Lazarević
Current measurement in
power electronic systems is a necessary part of the measurement
process. There are different ways for current measurement like using
current transformers or using the Rogowski coils which are not
precise enough in many applications and not suitable for use in
power electronic measurement systems. For that reason, the Hall
effect-based sensor can be used as a very precise alternative with
minimum external components. Presented in this paper is utilizing
the Hall effect current sensor ACS712 for current measurement with a
microcontroller system. The measurement with the Hall effect sensor
is described with an appropriate comparison of the measurement
values on a microcontroller system and multimeter and high precision
power analyzer Chauvin Arnoux 8335.
