... The X-600M is a multifunction web-enabled industrial I/O controller. It performs control, logic, and monitoring functions similar to that of a Programmable Logic Controller (PLC). However, unlike a PLC, the X-600M is designed for web-based applications from the ground up. No add-on software or hardw ...

... Despite their successful use in traction vehicles, voltage source inverters (DC VSIs) still suffer from many restrictions which limit their application areas. Because of the high switching losses of the GTOs and especially of the snubber circuits, the basic three-phase two-level DC VSI (Figure 7-21 ...
