Texas Instruments’ new MCU Software Eliminates FPGA to Achieve Sub-1 Microsecond Current Loop

Texas Instruments has introduced DesignDRIVE Fast Current Loop Software that makes C2000 microcontrollers (MCUs) to push current loop-performance below 1 microsecond. The combination of TI’s C2000 MCU portfolio and DesignDRIVE software delivers system-on-chip (SOC) functionality that simplifies drive control system development.

 

New DesignDRIVE Fast Current Loop Software outperforms traditional microcontroller (MCU) based current-loop solutions and can simplify designs by eliminating the field-programmable gate array (FPGA) typically used for external current-loop control. 

 

The technology unifies a hardware and software platform making it easier for engineers to develop and evaluate solutions for a wide range of industrial drive and topologies. As a key part of DesignDRIVE solutions, the new Fast Current Loop software allows developers to achieve higher control performance while saving valuable board space and simplifying thermal considerations. 

 

 

 

• Innovative sub-cycle pulse-width modulation update techniques significantly improve control loop bandwidths and potentially triple the motor torque response.

 

• A novel cycle-scavenging C2000 MCU needs just 460 nanoseconds for field-oriented control processing.

 

• Its complex controller replaces traditional proportional integration control and facilitates greater stability at higher speeds.

 

• Industrial drive systems designed with Fast Current Loop software on a C2000 MCU, like the TMS320F28379, delivers SOC functionality to reduce board space, complexity, and overall cost.

 

 

The new DesignDRIVE Fast Current Loop is available for the C2000 Delfino™ TMS320F2837x family of MCUs for advanced control applications start at USD11.32 in 1,000-unit quantities available in the TI store and at authorized distributors. Additionally, the C2000 DesignDRIVE development kit (TMDXIDDK379D) is available for immediate purchase for USD999.
