How many times have you poked around a circuit with a digital multimeter (DMM), read an AC voltage value, then gone on your merry way? Ever wonder if your meter is giving you peak value, average value ...
If you mostly deal with DC current, you might not think much of root mean square or RMS measurements. Sure, you’ve seen meters that have “true RMS” settings, but what does it mean? If you don’t know — ...
Extech Instruments announces its MA640 600A True RMS AC/DC Clamp Meters + NCV that has a higher accuracy rating then standard RMS meters. To use a clamp meter, only one conductor is normally passed ...

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 ...
Most isolated, offline SMPSs (switched-mode power supplies), including flyback, forward, and resonant, must operate at input voltages of 90 to 260V rms. Some cases even use line-to-line voltages of ...
