High-voltage transformer drive circuit

Published:2011/9/13 20:26:00 Author:Fiona | Keyword: High-voltage, transformer | From:SeekIC

Driver circuit uses the single-ended drive working mode,this circuit is simple and  its operational reliability is high.Power tube is drove by the signal from SG3524 chip. The ends of 11 and 14 pin are parallel output.When the SG3524 outputs high level,the power tube is conducted and stores energy in inductor L;When the SG3524 outputs low level,the power tube is off,it leads to the current flowing through the inductor L suddenly drops to zero,L has the potential.The pulse voltage of this counter potential is added to the input of high frequency transformer, driver transformer works.Meanwhile, the inductor L is used for impedance matching component of transformer.
