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 […]
Switching Triacs Safely using Zero Voltage (ZVS)
Zero-voltage switching (ZVS) for triacs is implemented by providing a controlled power to the load, through an ON/OFF switching of the line voltage, which is specifically at the zero crossing […]
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 […]
Surge free Transformerless Power Supply Circuit using zero Crossing Detection
The article explains a transformerless power supply circuit which works with zero crossing detection circuit to ensure a surge free output for the connected load. An AC information without a […]
