Power Factor (PF) is a measure of how a load draws power from the source. When the current phasor leads the voltage phasor, PF is leading and when the current phasor lags the voltage phasor, PF is ...

Domestic and international efficiency standards and customer demand for energy-sipping electronics are driving today's electronics engineers to make the most power-thrift devices possible. Domestic ...

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 ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

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 ...
