BIDIRECTIONAL, SOURCE / SINK DC SYSTEMS – SERIES TC.GSS

The bidirectional power supply series TC.GSS is intended for general industrial and laboratory operation and therefore do not fall under the regulations of Electric Power Generation and Distribution.
Nevertheless, the units dispose of a fully automated grid monitoring system able to detect phase voltage, current and frequency and islanding conditions as well.
In the case of a transgression of the programmed limits the unit comes to an immediate stop and the grid lines are disconnected. The TC.GSS firmware is based on a software successfully tested and certified.

This concept not only offers a very compact cabinet sizing, but also an extended modularity. TopCon.GSS systems can easily be designed to the customer’s needs in terms of voltage and power. An existing system can be upgraded at any time by simply adding further TC.GSS units with an absolute minimum of work!

• Excellent matching to grid with PFC (Power Factor Correction)
• Full modular concept, providing easy system upgrade
• Wide range of power 20-512 kW, expandable up to several MW
• Perfect galvanic isolation towards grid and ground (4500V)
• High dynamic response in both quadrants, fast quadrant crossover
• Operation in CV, CC, CP and internal resistance (IR) modes
• Full digital controls and peripheral operations
• Proprietary inter-unit bus system for easy master-slave operation
• Parallel-, serial-, parallel- & serial system configuration
• A wide range of controller parameter settings allows for adapting even to complex loads
• A number of interfaces is available to fit most digital/analog control requirements
• Full real-time system delivering time-consistent data
• Due to an active grid power interface, the harmonic content of phase current is minimized
• Advanced medium-frequency switch mode stands for excellent efficiency
• Special circuitry is used to minimize also common-mode voltage towards ground
• A control operation and service software is standard and included with the power supply
  This TopControl software includes:
  – 8 channel oscilloscope with access to any of the system variables
  – various trigger- and pre-trigger facilities
  – SCOPE images may be exported easily for factory assessment of user system
  – Zoom and autoScale functions for SCOPE images, cursor functions
  – Alarm and error management, programmable protection menu for voltage and current
  limiting with integrated time-off functionality for transient based error suppression.
  – VLS – a programmable, versatile limit switch function for monitoring output variables in
  terms of limit violation, value window monitoring, including hysteresis definition and timer
  functions acting on peripheral relays or digital outputs.

• Self-contained, very versatile built-in TopCon TFE function generator for generation of time dependent pulses and pulse trains with a time resolution of 50 usec
• The optional TFE function generator outputs may be directed to any of the controls, e.g. voltage, current, power
• Standard pulse shapes available as pre-sets
• User-defined arbitrary curves can be edited, stored and called up directly or imported from spread sheet programs e.g. EXCEL etc.
• The selected pulse shape is visible and scalable in a special PLOT window inside the ‘TopControl’ software
• In addition to time-domain pulses, the TFE provides a further unique feature: The Application
  Area Programming AAP. This feature allows to arbitrarily inter relate any output variable to
  another one by defining a function y=f(x) graph. As mentioned above, these graphs also
  may be edited, stored and recalled directly on the TopCon TC.GSS.
