effective powerAssume the terminal variables on a passive dipole (terminal voltage u(t) and terminal current i(t) ) are nonsinusoidal periodic time-fuctions: |
|
 |
(38) |
| Again these spectral displays can be represented as the sum of cosine- and sine- elements (applieance of the addition theorem ): | |
 |
(39) |
| For the active power exchange inside the dipole we obtain from: | |
 |
(40) |
| together with the property of orthogonality of the trigonometric function inside the interval of [t0, t0+T] | |
 |
(41) |
The constant components and the overtones themselves supply the known parts of the total active power exchange in the dipole.
