The authors were originally brought together to share research and applications through the international Danfoss Professor Programme at Aalborg University in Denmark. Personal computers would be unwieldy and inefficient without power electronic dc supplies. Portable communication devices and computers would also be impractical. High-performance lighting systems, motor controls, and a wide range of industrial controls depend on power electronics Depenbrock M. USA patent,
Ward Leonard control , also known as the Ward Leonard drive system, was a widely used DC motor speed control system introduced by Harry Ward Leonard in In early s, the control system of Ward Leonard was adopted by the U. Navy and also used in passenger lifts of large mines. It also provided a solution to a moving sidewalk at the Paris Exposition of , where many others had failed to operate properly. Connected to automatic anti-aircraft gun directors , the tracking motion in two dimensions had to be extremely smooth and precise. The Ward Leonard control system was widely used for elevators until thyristor drives became available in the s, because it offered smooth speed control and consistent torque. Many Ward Leonard control systems and variations on them remain in use.

Premium Membership. Learn from experienced power engineers. Once all the basic checks have been completed and the commissioning test sheet completed, the VSD is ready for energization. This will avoid problems with starting the motor in the wrong direction , starting with an acceleration time which is too fast, etc.

The rapid adoption of automation techniques in industry has increased the requirement for better process control. This has resulted in many new applications for AC variable speed drives VSDs to control the speed and torque of driven machinery. Variable speed drives VSDs are also used to meet particular starting and stopping requirements. The variable speed drives book promotes a sound understanding of how VSDs work and how to correctly select, install, commission and maintain them. There is also detailed coverage of many typical applications in process control and materials handling such as those for pumping, ventilation, conveyers and hoists. This book will benefit anyone associated with the use of VSDs in the industrial or automation environment.
