Transformers are a common component of traditional power supplies, however they may be large and heavy for low-power uses. A more compact design is provided by transformerless designs. However, the […]
Zero Crossing 220V AC Light Dimmer Circuit using IC 555
The post explains a high efficiency and versatile IC 555 based light dimmer circuit which works by phase control through zero crossing, thus eliminating noise and other issues associated with […]
Zero Crossing Detector Circuit
Many complex circuits and integrated circuits contain zero crossing detectors, but we will deal only with the detector here. The detector produces a pulse each time the mains voltage goes […]
