Flyback Transformer Based high voltage generators
This entry was posted on Thursday, January 31st, 2008 at 8:59 pm and is filed under 555, high voltage power supply.
Uses a 555 timer IC to generate a 720Hz triangle waveform (at pin 2 of the IC). This waveform is of about 50% duty cycle. This triangle waveform is compared to a fixed voltage with a comparator, IC2. The fixed voltage can be varied by potentiometer VR1. The output of the comparator is a 720Hz square wave of variable duty cycle. The potentiometer must be adjusted so that Q2 is near to 0% duty cycle (ie it spends the majority of the time off).
