In optimization power theory we can distinguish the three approaches: -the theory of instant power values -the theory of average power values (integral power) -the theory of instant.average power value. The theory of instant power uses the instant power and signals values i.e. p(t) = u(t)i(t) whereas the theory of average power uses the energy or average power terms i.e. P = (u(t), i(t)) (the dot...
The Fourier series method is frequently applied to analyze periodical phenomena in electric circuits. Besides its virtues it has many drawbacks. Fourier series usually have slow convergence and fail for fast changing signals, especially for discontinues ones. Therefore they are suitable to describe only quasiharmonic phenomena. For strongly nonsinusoidal signal analysis we propose the L 1-impulse...
