WebGeorge Royer, and so is often termed a "Royer" Converter. The following describes two fluorescent lamp circuits, both for 8W output, but designed for different input voltage ranges. Both circuits enable very high conversion efficiency. ... The application note has described practical implementation of a 'Royer' converter using Zetex.
The classic Royer oscillator circuit is used in some DC–AC inverters where square-wave output is acceptable for the load. The DC-DC converter form (Royer Converter) was quite popular in the 1970s, during which time it was typically implemented with bipolar transistors. However, due to the disadvantages mentioned … See more A Royer oscillator is an electronic relaxation oscillator that employs a saturable-core transformer in the main power path. It was invented and patented in April 1954 by Richard L. Bright & George H. Royer, who are … See more The Royer oscillator circuit consists of a saturable-core transformer with a center-tapped primary winding, a feedback winding and (optionally) a secondary winding. … See more Technology is always advancing, and the development of self-oscillating circuits is no different in this regard.

WebThe Royer converter oscillates at a frequency primarily set by T1’s characteristics (including its load) and the 0.068μF capacitor. LT1301 driven L1 sets the magnitude of the Q1-Q2 tail current, hence T1’s drive level. The 1N5817 diode maintains L1’s current flow when the LT1301’s switch is off.
