The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...
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 ...
This file type includes high-resolution graphics and schematics when applicable. For applications such as motor control or power supplies, it’s often necessary to know whether the ac line is at 120 V ...
