Case Studies
Current controller for inductive control in the steel industry
Initial situation
The current controller was developed for an industrial customer in the German steel industry to enable precise and stable current control in inductive processes.
Charge/discharge operations for lithium-ion batteries controlled via I2C bus
Initial situation
TPS Elektronik GmbH developed a compact and portable charge/discharge device for lithium-ion batteries for a customer in the medical sector, with a focus on safe and reliable energy management.
In addition to the competencies described above, we offer PCB design and layout, prototype and series assembly, test concepts, and turnkey manufacturing of complete electronic systems.
