DC Flyback Transformer with Single Transistor Driver

!: DC Flyback Transformer with Single Transistor Driver

This is a DC flyback transformer from a 32" Sony TV. It is driven by a single obsolete 2N5685 transistor. There are 7 primary turns and 3 feedback turns. The voltage divider consists of 5 watt 270 ohm and 22 ohm resistors. With 4 primary turns the arcs were longer, but the transistor got too hot after a few minutes of operation. Primary polarity was compared to give the longest arcs.
