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.
