What will I learn?
The Diac and Triac Course gives you practical skills to design and refine reliable AC dimmer circuits. You learn device fundamentals, phase-angle control, waveform behavior, and harmonic impact, then move into EMI, thermal management, and safety standards. Through focused design steps, testing methods, and troubleshooting techniques, you gain confidence to create robust, production-ready dimmer solutions.
