the When the input ac voltage reverses and becomes negative during the negative half cycle current flowing through the conducting thyristor decreases and falls to zero. Thus the ON thyristor naturally turns off, when the device current falls to zero. Phase control Thyristors which are relatively inexpensive, converter grade Thyristors which are slower than fast switching inverter grade Thyristors are normally used. For applications upto 400Hz, if Triacs are available to meet the voltage and current ratings of a particular application, Triacs are more commonly used.Due to ac line commutation or natural commutation, there is no need of extra commutation circuitry or components and ac regulator (termed as ac to ac voltage altro rontrollers are converter) with balanced resistive (star connected) load is shown in Fig. 27.1. It may be noted that the resistance connected in al three phases are equal. Twc thyristors connected back to back are used per phase, thus needing a total of six- thyristors. Please note the numbering scheme, which is same as that used in a three-phase full-wave bridge converter or inverter, described in module 2 or 5. The thyristors are fired in sequence (Fig. 27.2), starting from 1 in ascending order, with the need help with python...paste indented code here QUESTION 2 1.
