I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

Power factor correction is a frequently misunderstood topic. Improper techniques can result in over-correction, under-correction, and/or harmonic resonance, so it can be helpful to understand the ...

The FAN7529 is an active power factor correction (PFC) controller for the boost PFC application that operates in the critical conduction mode (CRM). The critical conduction mode boost power factor ...

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 ...

Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor power factor will result in increasing electrical efficiencies and will reduce the overall use of ...

Linear Technology Corporation’s LT3798 is an isolated flyback controller with single stage active power factor correction (PFC). Efficiencies greater than 86% can be achieved with output power levels ...
