This is my first attempt at posting so bear with me. I'm interested in understanding the principles governing the sizing of capacitors used in ferroresonant or constant voltage transformers. I've recently experienced the failure of a transformer used in a battery charger circuit that overheated (read burned up) and believe it was due to the size of the capacitor. If I understand the relevant principles, it was oversized by a factor of 4. I have read the section in chapter 9 which shed quite a bit of insight, but I would like some examples illustrating the same circuit with different size caps. I'll express my gratitude now for any responses. Thanks, Anomaly :unsure:
