It is essential to a stable supply the required voltage, which is maintained regardless of transients and spikes of current consumption . It is also necessary to filter out components of the AC, created by a sudden noise or current pulses .
Ni muhimu kwa ugavi imara voltage required, ambayo ni iimarishwe bila kujali transients na spikes ya matumizi ya sasa . Ni muhimu pia kwa chujio nje vipengele wa AC, umba na kelele ghafla au kunde sasa .
