About the Author
Taylor Morey is a Professor of Electronics Engineering Technology at Conestoga College Institute of Technology and Advanced Learning in Kitchener, Ontario, and design consultant with over 30 years experience in power supplies.
Taylor Morey, currently a professor of Electronics at Conestoga College in Kitchener, Ontario, Canada, is co-author of an electronics devices textbook, and has taught courses at Wilfred Laurier University in Waterloo. He collaborates with Keith Billings as an independent power supply engineer and consultant, and previously worked in switchmode power supply development at Varian Canada in Georgetown, and Hammond Manufacturing and GFC Power in Guelph, where he first met Keith in 1988. During a 5-year sojourn to Mexico, he became fluent in Spanish and taught electronics engineering courses at the Universidad Católica de La Paz, and English as a second language at CIBNOR biological research institution of La Paz, where he also worked as an editor of graduate biology students’ articles for publication in refereed scientific journals. Earlier in his career he worked for IBM Canada on mainframe computers, and at Global TV’s studios in Toronto.

Chapter 6: Self-Oscillating Flyback Converters
...6.5 Control CircuitA very simple control circuit is used. The diode of the optical coupler OC1 is in series with a limiting resistor R9 and a shunt regulator U1 (Texas Instruments TL430).
When the reference terminal of the shunt regulator V1 is taken to 2.5 V, current will start to flow into the cathode of V1 via the optocoupler diode, and control action is initiated. The ratio of R12 and R11 is selected for the required output, in this case 12 V.
The optocoupler transistor responds to the output control circuit so as to apply a bias current to R3. A voltage divider network is formed by OC1 and R3 and the base of Q2 as the optocoupler current increases, and so the ramp voltage required across R4, and hence the collector current required to turn Q2 on and Q1 off, will be reduced. (A more complete description of this control circuit is given in Sec. 7.4.)
As Q1 starts to turn off, its collector voltage will go positive, and the collector current will be diverted into the snubber components D2, C5, and R5. The voltage across R5 results in an increase in base drive voltage
