Power Factor improved by Variable Speed AC Drives

Figure 2.The current phasor I rotates in phase with the voltage vector uR, but it is lagging the voltage phasor uL and leading the voltage phasor uC.All phasors rotate counter-clockwise. Because the uL and uC are pointing in opposite directions, they are subtracted and the difference uX is the reactive component of the total system voltage. The uR is the active or real component and the phasor ...
