The best part about post-mortem teardowns of electronics is when you discover some unusual design features, whether or not these are related to the original fault. In the case of a recent ...

Various factors like the enhanced global energy consumption brought about by the advancement of industrialization besides urbanization, are also putting pressure on the power grids. This makes PFC one ...

Power factor correction is a crucial aspect in optimizing the performance of electrical systems, both in residential and industrial environments. Theoretically, publicly supplied power should be clean ...

The sole definition of power factor correction is defined as the real power to apparent power. The definition of real power is the average over a cycle of the instantaneous product of current and the ...

ABSTRACT: By adding a suitable LC filter to the input of a Buck converter, a high-power-factor buck converter is proposed. The converter can operate in the discontinuous-output-current mode operation.

This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

A new type of high power LED drivers is proposed by adopting an improved two-stages non-isolated configuration. In order to improve power factor and achieve accurate average current control under ...

Abstract: Electric power is delivered most efficiently from utilities to end users when the load draws current at unity power factor. Traditional ac-to-dc power supplies that use a rectifier/filter ...

Abstract: Switching power supply is widely used in many industrial fields. Power factor correction (PFC) circuits have tendency to be applied in new power supply designs. The input active power factor ...
