A firing control Weight Plate Pin scheme for a three-phase fully controlled thyristor bridge dual-converter is described.By adapting the cosine wave crossing method, in the scheme, the converter operates as a linear power amplifier.The firing circuit has a fast response for triggering angle correction.The scheme requires minimum number of integrated circuit component since it utilizes the HONEYDEW SHAMPOO same circuit for both rectification and regeneration modes of operation.The experimental waveforms are correlated with predicted waveforms.
