Abstract :
Typical problems associated with voltage source inverter type VFDs (variable-frequency drives) and their surroundings are discussed. Suggestions are put forward to identify problems and to take corrective steps to reduce the overall down-time of an installation. The suggestions made in certain circumstances may not be the best in all cases. Also, for installations using VFDs, suggestions are made to improve the overall system performance by introducing passive and/or active filters and by making use of programmable logic controllers and computers to monitor and control process parameters
