TDK-Lambda Americas Inc., High Power Division Compact High Voltage Power Solutions 1-50 kV, 60kW to 1MW

A modular and scalable design approach that use multiple standard ALE 303 series 50kW power modules to deliver raw high voltage DC power for the system. The outputs of each 303 power module are combined using a simple Junction box which can also accomodate any necessary output filtering and voltage/current feedback required. The complete system and individual power module outputs are centrally controlled by a Master Controller which offers both local and remote user interfaces. A Master Controller generates all control signals required by each of the 303S power modules, and enables both local or remote user control of the system output voltage and current. The use of a multi-phase variable frequency control technique, results in low output voltage ripple without the need for large output energy storage filter capacitors. The controller interfaces to each 303 power module (or bank of 303 power modules), and to the Junction Box to provide system output voltage and current feedback, and operating status.
