Switching generator based on Toshiba TL494. Switch.Freq = 300KHz..500 KHz

СКВАЖНОСТЬ is ratio of pulse period to pulse duration, reciprocal od Duty Factor pulse duration to pulse period. All after switch.transistors should be erased and connected as above sch.

L2&C1 must be tunned to 50Hz Russia, or 60Hz America. Volatge at L4 should be 600V or better. Output could be via capacitors or Tesla Bifilar or other useful configurations.

Tr1 & Tr2 are identical transformers, 220V input coil, 30V output coil (alternating current) 200--300Wt.

Video experiment

Output could be like this
