This is a CMOS IC (CD4033) based circuit which can be used to detect presence of AC mains voltage without any electrical contact with the conductor carrying AC current/voltage. Thus it can be used to ...
The input-rectifier stage of anoffline power supply converts anac-line voltage to a dc voltage, whichpowers a dc/dc converter. If you configurethe rectifier section as a full-wavebridge for a ...
