  • ADE7880 - 3 phase 3 wire delta configuration

    Hi,

    As per the ADE7880 datasheet pg. 43, in three phase three wire delta configuration, Phase B active, reactive and apparent powers are 0.

    So, I would like to know if there is a way to find out the Phase B power data in three wire delta configuration…

  • 3 wire 3 phase 115V(L-N) 380-665Hz prfc application

    Could you please suggest a analog pfc controller for 3 wire 3 phase, 115Vac, 380-665Hz, 380Vout, 800W, min 0,95 power factor?  I couldnt find vienna rectifier example or application note at Analog device.  My second alternative is 3 phase boost topology…

  • ADE9078 3相3線Delta接的問題

    最近使用ADE9078的三相電能計量, 遇到以下的問題.

    問題介紹:

    1. 規格書有提到, 計算總功耗(有功, 無功和視在), 須將A相和C相的貢獻相加,

        而我運算的結果, 只有"有功"的算完的數值是正確的, 其餘無功以及視在的數值有落差.

    硬體介紹:

    三相是採用3線Delta, B相接地. 使用EVAL-ADE9078EBZ開發板+EVAL-SDP-CB1Z.

    電流部分使用CT(600:1)

    參數設定:

    VCONSEL設為1, ICONSEL設為0,

  • 3-phase system measurement and 3 single-phase system measurement by ADE9000, ADE9078

    Hello,

    Can we measure a 3 phase system and a 3 single-phase by same circuit using ADE9000 or ADE9078? Off course the meassurement points of the 3 phase system and the 3 single-phase system are different. If no, could you please advise me the connection in…

  • ADE7880 3 phase 3-wired(Delta mode) How to calculate ITHD,VTHD value

    Hello 

    I use ADE7880 to analyze total harmonic distortion(THD) in 3 phae 3-wired(Delta connection)

    It's OK in ITHD each phase,the value is what I expect

    But the value of VTHD is unexpected(each phase), VTHD value is totally different from testing…

  • ltc6957-3 : always 3.3V at the output

    We are trying to double a clock frequency with the circuit below.

    The problem of the circuit is when we put a signal from an SMA (adapted 50 Ohms) the output of my LTC6957-3 stayed
