Tesla transformer on the Brovin Kacher from 220 volts
The circuit is supplied with a voltage of 220 V which, before going to the main generator part of the kacher, straightens through diode D1 and goes down by means of a choke, I used a 12 volt transformer as a choke that is turned on by a winding 220, simply speaking, we take two wires to which the transformer is connected 220 and one of them is also connected to 220 and the second goes to power the kacher to the capacitor C1. Now let's move on to the resistors, R2 can be used with average power, I used the Soviet medium size, as for R1, I simply did not have such a naminal and I used 4 to 12 KΩ high power and all the resistors remained cold even after a long work. Now let's touch the transistor with the most scarce part of the installation. KT828 can only be taken as a last resort if there is no way to get imported ones, namely, Panasonic's transistor S5244A showed excellent work, but do not repeat my mistakes, do not try to remove the choke or set very small,in my case, I removed it altogether and the transistor exploded rather not weakly. You can use 2SA1943 and similar with such parameters of voltage and current, the transistor as usual in these cases is placed on the radiator.
