Designing a Trailing Edge Dimmer Circuit - Nothing Untoward
33.9 parsecs away

Travel
| [AI summary] This is a detailed account of the design and implementation of a trailing edge dimmer circuit for a lamp. The author explored various components and concepts, including current sources, pulse generation, and the challenges of achieving a linear ramp for dimming. Despite the project's complexity, the author found the dimming performance to be less than ideal due to nonlinearity in the ramp and flicker in the output. The project concluded with a decision to pursue an alternative solution, such as a rotary switch, instead of a dimmer.
