STEADY-STATE POWER ANALYSIS
LEARNING GOALS
Instantaneous Power
For the special case of steady state sinusoidal signals
Average Power
Power absorbed or supplied during one cycle
Maximum Average Power
Transfer
When the circuit is in sinusoidal steady state
Effective or RMS
Values
For the case of sinusoidal signals
Power Factor
A measure of the angle between current and voltage phasors
Complex Power
Measure of power using phasors
Power Factor
Correction
How to improve power transfer to a load by “aligning” phasors
Single Phase Three-Wire
Circuits
Typical distribution method for households and small loads
