  • TIDM-02002: Setting comparator output inversion for an inverted Rogowski coil

    Resolved
    Part Number: TIDM-02002 Assuming that I put the Rogowski coil on the secondary side in reverse, should I invert the output from the comparator from this: void CLLLC_HAL_setupSynchronousRectificationAction(uint16_t powerFlow) { if(powerFlow == CLLLC_POWER_FLOW_PRIM_SEC…

  • RE: TIDA-01063: Sensing current range of PCB Rogowski sensor

    Resolved
    Linda, Can you provide more details on the required accuracy for this system? Rogowski coils have a wide measurement range, but you may have worse readings at the lower currents due to the lower output voltages produced at these currents. In the TIDM…

  • RE: ADS131A02: Rogowski Coil Interfacing for Constant Current Closed Loop Feedback

    Karan, One other design resource that I'd forgotten to mention is that there is a TI-Design for an e-Meter, using Rogowski coils for the current measurement. Again, it's not your particular application, but there may be more information about the Rogowski…

  • RE: Improve the anti-interference ability of the chain

    Resolved
    Hi Wendy, Q: Do you have some recommendation for us to improve the EMC of the ADC? The high voltage spikes or inductive kickback are due to Ldi/dt from the Rogowski coil during On or Off period. Since I do not have specific inductance value and di/dt…

  • RE: CCS/MSP430F67791A: MSP430F67791A

    Hello, I'm assuming that you're using the EVM430-F6779. There are several TI Designs based on this EVM. These include: High Accuracy Three-Phase Electricity Meter with Tamper Detection (TIDM-THREEPHASEMETER-F6779) Total Harmonic Distortion Measurement…

  • RE: OPA211: Inverting application of OPA211 failure

    Resolved
    Hi Eric, 1, My circuit is used in current measure of the inverter's low-side phase leg. The accuracy of current sampling is very high (0.1% or higher). What is the best topology? Please take a look at the following threads. https://e2e.ti.com/support…
