You can make the pulse output transformer T by yourself, the primary winding of it is 30 turns, the secondary winding of it is 45 turns, they are the No. 22 enameled wire. The transformer core has no special requirements, it ensures the turns of the primary and secondary coils. The VS can use the ordinary thyristor 3CT20, the positive and negative blocking peak voltage is more than or equal to 50V, the rated average forward current is 20A. The single-junction tube V2 is the BT33C or BT35C. According to the general characteristics of single-junction tube, the peak voltage Vp is not the fixed value, it has relationship with the voltage divider ratio n and the external voltage Ub2b1. You can change the value of Up by selecting the different single-junction tubes or changing the external voltage.
