The variable frequency drive industry is growing rapidly, and it is now more important than ever for technicians and maintenance personnel to keep VFD installations running smoothly! Part of the Electrician's Technical Reference Series, this field guide is ideal for gaining access to information about variable frequency drives, including how they work, how to apply them, and how to troubleshoot them. A hands-on reference, Variable Frequency Drives contains sufficient information for a technician to troubleshoot any AC variable frequency drive, virtually eliminating the need for manufacturer-specific manuals! Both industrial and commercial variable frequency drive applications are addressed, with discussion of installation issues, troubleshooting, metering, sizing and selection, energy savings with variable frequency drives, and more. A final chapter preps readers for future developments in variable frequency drive technology, while appendices feature addresses of relevant organizations and a bibliography of suggested readings.The SCR converter has more capabilities than the diode converter because it is more controllable. However, for VFD ... Silicon- controlled-rectifier commutation notches create dramatic disturbances on the supply and simply cannot be tolerated in facilities. As SCR designs ... The latest technological design method for inverters is based around the insulated-gate- bipolar transistor (IGBT). This transistor isanbsp;...
