INSTANTANEOUS REMEDY DEVICE FOR FREQUENCY CONVERTER WITH VOLTAGE MIDDLE CIRCUIT |
摘要 |
An arrangement for bridging brief network failures in intermediate-link converters converts the kinetic energy in load motors into electrical energy by reducing the frequency of the converter. Such a frequency reduction is performed in accordance with the value of a control deviation signal corresponding to the difference between desired and actual frequencies of operation of the converter. The control deviation signal is produced by the combination of a PI controller which is coupled at its output to an integrator circuit. The integrator circuit controls the frequency and voltage of the converter. |
