PEPPER is ideal for the control, characterization and testing of power components such as power supplies, transformers, inductors, actuators and motors. A special feature of this amplifier is that it can control output of both voltage and current and that all kind of load impedances (from capacitive to inductive) can be connected. PEPPER is extremely flexible, accurate, efficient and broadband. The design of this amplifier can be integrated for unique applications in a customer-specific solution.
PEPPER is a 4-channel platform which is made up of state-of-the-art Gallium-Nitride (GaN) FETs. The output signals are well filtered so that interference signals, such as may occur with conventional motor drives, have no effect. EMC compliance will be considerably simpler and the filtering also reduces disturbances within the system itself.
PEPPER is implemented as an FMC (FPGA Mezzanine Card) card so that it can be connected to the MINT of 3T. Through the use of FMC it is compatible with most of the third-party FPGA or microcontroller development boards. In combination with the MINT, it is a very flexible amplifier in which the control algorithm can be implemented in the FPGA part or the ARM portion of the Arria V System-On-Chip.
To reduce the design effort and simplify verification, the control algorithm can be developed in MATLAB / Simulink. After correct simulation of the control algorithm, Model Based Design can be used to generate VHDL / C / C + code. Using Hardware-in-the-Loop (HIL), the control algorithm can then be validated on PEPPER with MATLAB / Simulink.
