Practical Examples of Power Factor Correction It is seldom feasible or practical to correct the power factor to unity. To do so, in most cases, would result in a leading power factor at times. This would increase the kVA in respect to the kW just as much as a lagging power factor. Neit...
NCP1650 Power Factor Controller The NCP1650 is an active, power factor correction controller that can operate over a wide range of input voltages, and output power levels. It is designed to operate on 50/60 Hz power systems. This controller offers several different protection methods to assure ...
This use case shows how parametric EM simulation helps to optimize the layout of an electric-vehicle on-board charger (OBC). The OBC typically has two power stages: a DC/DC stage for output voltage/current regulation and an AC/DC stage for voltage rectification and power-factor correction (...
SAPF typically uses two-stage voltage inverters (VIs); these give acceptable results in terms of power factor correction and THD of current elimination50. However, for high-power and medium applications, this type of inverter is no longer suitable because it requires power components that can wit...
