Royer generator on bipolar transistors: what it is and how it works

Introduction

Today we will try to understand what a Royer generator is using the example of a CCFL converter, assemble its prototype, and also study the principle of operation.





Background

A non-working scanner fell into my hands just now, there was no point in repairing it, so it went for spare parts. I took off the CCFL (cold cathode fluorescent lamp) lamp and converter from it and decided to play with them.

Testing

Now we can shoot arcs and power the CCFL tubes from this driver. The power supply of the circuit is 12 volts.
