Calculate the peak-to-peak ripple voltage Vpp of the full-wave bridge rectifier with capacitor filter circuit and generate the output waveform. Then, to determine the peak-to-peak ripple voltage Vpp ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

More and more portable devices now use ceramic capacitors for filtering of dc/dc-converter inputs. Ceramic capacitors offer the advantages of small size, low ESR (equivalent series resistance) and ...

Fig. 1: The dimmer circuit schematic showing the filtering capacitors. Rob Atkinson, K5UJ, is an engineer out of Saint Charles, Ill., and one of the many readers who enjoy the DIY projects we feature ...

Although SPICE can be a powerful tool, there are pitfalls in relying solely on simulation. To avoid unpleasant surprises, it's imperative that a SPICE simulation be anchored to a detailed ...

A PQ expert can link an abnormal current or voltage waveform to an abnormal condition on a power system just as a handwriting expert matches a signature to a person. Many facilities now have online ...

Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

Restrikes or re-ignitions occur when the dielectric strength of the open gap, during contact parting, is not great enough to withstand the recovery voltage across the open gap. With a capacitive load, ...

In the 1960s, mainframe computers took up entire rooms. By the 1980s, there were individual workstations and just a few decades later, laptops and smartphones became ubiquitous. Today’s technology is ...

A research team led by Prof. MENG Guowen and Prof. HAN Fangming from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS), along with Prof. WEI Bingqing from the ...
