ABSTRACT:
A control unit for an externally commutated converter of the type which forms firing pulses for the converter rectifiers from a comparison of a synchronization voltage and a variable d.c. voltage in which the synchronizing voltage is fed to an amplifier followed by a limiter and integrator for smoothing purposes with the output of the integrator fed back to the input of the amplifier. In the simplest embodiment the limiting is accomplished through saturation of the amplifier. In another embodiment an additional integrator is provided, the output of which is coupled back to the output of the amplifier through a pair of diodes in parallel with opposite polarity.
