    LTC1967 RMS-DC Converter transformer issue

    Hi everyone, I'm trying to read RMS voltage with LTC1967. I have seen this post before "https://www.electro-tech-online.com/threads/ltc1966-rms-dc-converter-issue.158100/" and clearly understand circuit. My question is that do I have to use a transformer? because I don't have big area to put...

    Output current from MOSFETS (bridge) before trafo?

    I having a concern about the what kind of current that I have after the MOSFETs (in the transistor bridge) before transformer. Before the MOSFETS I have a DC current from an AC/DC converter stage. So I am a bit confused if the current before the transformer is average, peak-to-peak or RMS...

    Change the current from a voltage source?

    So what I understand so far, if I want to have 16 A out from a voltage source (230 V RMS) which is 325.269 V in amplitude (peak), can I simply add an resistor in parallel to achieve that? R = 325.269 V / 16 A = 20.329 ohm Do you think guys if I am on the right track? So if I am want simply to...

    dsPIC33F to measure RMS value of current

    Hi I am using a dsPIC33F micro to measure energy drawn from a battery. The battery is connected in a solar energy system. The output of a MPPT controller charges the battery during the day and in the night it is fed to a sine wave inverter that drives AC loads. The battery current is measured...
