Usando el PSPICE orientado al analisis de los circuitos del controlador booster instalado en CVG Venalum

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.
