A general method for measuring AC high voltages is to use a voltage divider, with two resistors in series. The resistors are selected so across one of the elements is some arbitrary fraction (like ...

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 ...

As part of the move to increase efficiency, power supply units are moving from the bottom trays to their own racks.

Newnan, GA. Yokogawa Meters & Instruments Corp. has announced that it has developed the LS3300, an AC power calibrator that can accurately and stably produce a wide range of AC power outputs for the ...

The voltage sag protection system from case study 2 was installed in a chemical plant that produces methanol and ammonia. The development of power electronics technology and applications in industrial ...

The war of the currents was fairly decisively won by AC. After all, whether you’ve got 110 V or 230 V coming out of your wall sockets, 50 Hz or 60 Hz, the whole world agrees that the frequency of ...
