Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

Schweitzer Engineering Laboratories has released the SEL-734W Capacitor Bank Control and SEL-8340 Wireless Current Sensor solution, offering utilities a way to improve distribution power quality and ...

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...
