Applications, such as laser cutting, are pushing the boundaries of PSU performance. The latest laser cutters use high frequency pulsed power to cut a wider variety of materials, faster, with greater precision, and often without the need for post process machining or specialty cutting tools. This is part of a general trend of laser cutting machines becoming more sophisticated and automated to better compete with traditional machining technologies. Hence, laser cutting machines have been increasingly used in automotive, shipbuilding and aviation manufacturing.
