%X this paper shows the usefulness of the pspice circuit simulator to understand the operation of the booster-cell controller installed in cvg venalum. the aluminum reduction process requires of a high power dc current source. the booster-cell equipment is able to feed the reduction cell using a thyristor-rectifier. this system has incorporated several stages of analog and digital circuits: the buffer units, a voltage integrator, a current regulator, the gating module, an attenuator voltage, a conditioner current amplifier and others circuits. actually, the technical information not is enough to understand the transient-state response of these circuits. the considered pspice examples represent a virtual laboratory of the system. performing the simulations, observing the voltage waveforms, and determining waveforms components, the technical staffs have a better appreciation of booster-cell circuits. whenever is possible, the simulation results are compared with theoretical ones gives by equations developed. the simulation results can be used as technical support during maintenance operations.
