Abstract: A new optimizing method of mathematical analytical modeling of
induced current for electronic anti-fouling technology is used in the present
study to solve the problem of large calculated amount and complex deducing
process caused by traditional segmented function method under different
excitation signal, and an exact 2D finite element method is used to calculate
induced current in a real electronic anti-fouling system, and the finite
element calculation results can fit well with the results calculated by the
optimizing analytical model of induced current under the excitation signal with
different waveform. Furthermore, the average power density of induced current
and the efficiency of energy transformation for EAF system are calculated to
estimate the system performance under different excitation signal. The
calculation result shows that: 1 the positive – negative square wave
excitation signal can make the largest average power density of induced current
and the sine wave excitation signal makes the smallest; 2 the sawtooth wave
excitation signal can make the highest efficiency of energy transformation and
the positive – negative square wave excitation signal makes the lowest.
