In this episode, Surbhika developed such a circuit to enable dimming of commonly used AC lights bulbs at home. This was an interesting DIY project as it meant realizing one of the fundamental concepts in power electronics and control theory to generally usable hardware.</p> <h3 id="mcetoc_1gvhefkmn0">Watch the

1 posted to Documents by tariq.ahmad on 5/3/2023 6:50:22 PM<br /> <p>Dimmer circuits consisting of Phase Angle Control are used to efficiently adjust the AC power delivered to the AC loads by controlling the conduction angle. In this episode, Surbhika developed such a circuit to enable dimming of commonly used AC lights bulbs at home. This was an interesting DIY project as it meant realizing one of the fundamental concepts in power electronics and control theory to generally usable hardware.</p> <h3 id="mcetoc_1gvhefkmn0">Watch the
