Two-Level Three-Phase Inverter Module

PWR-TPI6020 - Two-Level Three-Phase Inverter Module

48 V/20 A Two-Level Three-Phase Inverter Module

The PWR-TPI6020 module is a modular, multiple half-bridge inverter with three phases and individual gate driver control. This module is fully compatible with Speedgoat FPGA technologies, such as the IO324, IO336 or 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 suitable 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 Speedgoat I/O modules, the PWR-TPI6020 is ideal for closed-loop applications using MATLAB^® and Simulink^® with closed-loop rates of up to 100 kHz and faster using HDL Coder™.
