PWR-TPI6020 - Three-Phase Inverter Module 

48 V/20 A Three-Phase Inverter Module 

The PWR-TPI6020 module is a modular three-phase inverter with individual gate driver control. This module is fully compatible with Speedgoat FPGA technologies such as the IO397 I/O modules and can easily be connected to any real-time target machine. 

The module is optimized for use as a three-phase inverter. Its modular design, however, also makes it ideal as a full bridge or a high-side or low-side driver.  

The PWR-TPI6020 enables you to control each single gate driver, and monitor the phase current and bus voltage of your closed-loop applications. 

When used with FPGA I/O modules, the PWR-TPI6020 is ideal for closed-loop applications using MATLAB® and Simulink® with closed-loop rates up to 20 kHz and faster using HDL Coder™. 

Key Features

  • Three half-bridge phases with individual gate control:
    • 12 to 48 VDC nominal DC Bus voltage
    • Up to 20 A continuous RMS current
    • Up to 50 kHz switching frequency 
  • Continuous monitoring of voltage, current and temperature
  • On-board protections for overvoltage, overcurrent, overtemperature and deadband
