Zero voltage switching

Switching frequency in Power Supply Having a higher switching frequency helps in reducing size of components such as transformers and inductors and help achieve higher power density. A smaller size will typically also mean lower cost ... Choose motor starters (VFD or soft starter) base on your application A soft starter is incapable of speed-control. It only restricts starting current by applying the voltage in a ramp. The consequence is that for much of the ramp, the torque is severely compromised, ... Soft Starter Working Principle The control core of Gozuk HV/MV solid soft starter cabinet is composed of a HV motor soft starter integrated controller, a thyristor dynamic safety monitoring and protection unit, a thyristor firing ... Voltage transient in induction motor Voltage transient occurs whenever there is a sudden change in current in an inductive device. Inductors resist a sudden current change. In electric motors this occurs at start up when the contactors ... Inrush current on motor start up Inrush is something we have always had to deal with, especially with motors that are direct on the line start. The inrush can be as high as seven times the nameplate current. The damage created can ...
