So, this is it.

schematics

pcb


test

signal from IGBT gate, without power on collector, 5V/5mks/cell





transformer, primary coil

lower side rectifier

capacitors


upper side rectifier, quad of BR1010 and start module withBTA41



partly collected

ventilator under main transformer

signal from second coil of main transformer


testing - incinerated two electrodes 3мм



Or possible do else on such scheme:


But it is necessary to make sure that minimum duration of the pulse it is enough for feeding upper shoulder of IR2110.
