Three Phase AC Current Measurements Using Current Transformer Reference Design
Description
The TIDA-00753 reference design demonstrates high accuracy wide range AC current measurement for a three phase motor using the INA199 zero drift current shunt monitor. The design also has low power consumption of 25mW for Gain stage of 200 as compared to a discrete solution. The design footprint and BOM cost is much smaller than a discrete solution due to the integrated high precision resistors inside the INA199.
Features
- 0.5 % Accuracy (Uncalibrated) for 10 to 100 % of Full Scale Primary CurrentPower Consumption of 25 mW for Gain StageSmall Footprint no need of External Resistors for Amplfication
Applications
- HVAC controller
- Door operator drive control
- Merchant telecom rectifiers
- HVAC motor control
- HVAC valve & actuator control
- Powertrain current sensor
- OBC-wireless charging
