3T: Your partner for electronics & embedded systems

PEPPER was designed for precise control, characterization, and testing of various power components, including power supplies, transformers, inductors, actuators, and motors.

One standout feature of this amplifier is its ability to regulate both voltage and current outputs while accommodating a wide range of load impedances, from capacitive to inductive.

PEPPER excels in flexibility, accuracy, efficiency, and bandwidth. Its adaptable amplifier design can seamlessly integrate into custom, application-specific solutions for our valued customers.

PEPPER - An Adaptable Solution with Versatile Applications

PEPPER is a 4-channel platform featuring cutting-edge Gallium-Nitride (GaN) FETs. Its output signals are meticulously filtered to eliminate interference, ensuring that typical issues seen with conventional motor drives have no impact. This not only simplifies EMC compliance but also minimizes disturbances within your system.

Implemented as an FMC (FPGA Mezzanine Card), PEPPER seamlessly connects to 3T's MINT development board. This FMC design ensures compatibility with most third-party FPGA or microcontroller development boards. When paired with MINT, PEPPER becomes a highly flexible amplifier, allowing you to implement control algorithms in either the FPGA or the ARM section of the Arria V System-On-Chip.
To streamline design efforts and verification, control algorithms can be developed in MATLAB/Simulink. Once validated through simulation, a Model-Based Design approach generates VHDL/C/C+ code. Hardware-in-the-Loop (HIL) testing enables validation of the control algorithm on PEPPER using MATLAB/Simulink.

PEPPER can function as both a source and a load, with fully adjustable output characteristics. This versatility makes it ideal for precision actuator control and the characterization of various components, including:

  • Voice coil or Lorentz actuators

  • Solenoids

  • Variable reluctances

  • Motors (DC, brushless, AC induction, sensorless, ironless, 2 or 3 phases)

  • Piezos

  • Laser and LED modulation

  • Heaters

  • Precision programmable power supply, voltage / current limited

  • Active loads

  • Battery cell charging, discharging, characterization (load curves, lifetime, automatic endurance tests)
