TC.GSS Multi-Application DC Power Supply

The accuracy and dynamics in both constant voltage and constant current mode of the TC.GSS series, as well as the ability to easily change between different multi-unit configurations, make this series the ideal power supply solution for bidirectional R+D tasks and test bench applications such as testing of any power conversion systems (PCS) or testing of converters for energy storage systems (ESS).

For testing inverters, the bidirectional power supply unit can replace and simulate a DC link or energy storage element in the test setup. In addition to stable constant voltage control, the TC.GSS power supply units offer an internal resistance simulation or even a sophisticated programmable battery simulation (BatSim) with dependency on cell chemistry, state of charge, load current, polarization effects, and further parameters. All relevant calculations for the simulation models are performed onboard the power supply unit in real-time. In addition to any time-dependent programming of voltage, current or power, the function generator (TFEAAP) also offers the application area programming feature. This allows to set the DC output voltage or current or power as a function of any of the input values IDC, UDC, or PDC. The functional relationship is given by a user-defined curve whose values are managed by csv import/export. In this way, a wide variety of nonlinear electrical two-pole networks can be defined, for example a fuel cell simulation with a voltage/current dependence. Embedded calculation onboard the TC.GSS assures real-time simulation.

For demanding applications such as testing of drive inverters, Regatron offers the full range of interfaces and safety features. For automotive applications, integration is usually carried out via the CANmp real-time interface with 1 kHz data rate. The TC.GSS modules offer a safety interface (ISR) which provides easy integration into the test bench without the need for costly external DC or AC contactors. TC.GSS modules or systems offer performance level c or e (PL c / e) in accordance with ISO EN 13849-1. In the event of an emergency stop in the test bench, residual energy from the rotating elements should be discharged as quickly as possible. Regatron offers an additional DC discharge unit (DDU) for this purpose, which ensures that the energy is safely discharged via low-ohmic resistors.

REGATRON’s bidirectional und regenerative TC.GSS battery testers provide a multitude of properties making them ideal test units / systems for all kinds of electrical storage elements testing:
