AC power analysis
Instantaneous and Avg Power
Power Consumption
R 성분 only
Instantaneous Power
p(t) = i(t)* v(t)
Avg Power
Pavg = 1/2 V
I
cos(각도V-각도I)
Maximum Power Transfer
등가회로 구성
ZL = ZTH*
Rth = RL
Pavg,max
Complex Power
S = 1/2
(V)
(I)^*
S = (Apparent Power)*cos(각도V - 각도I)
Apparent Power [VA]
S = (Avg Power) + j*(Reactive Power)
Effective Value
Root Mean Square
S = Vrms
(Irms)^
Power Correction
S = P + jQ
