TIDA-00281
Automotive 48-V, 1-kW Motor Drive Reference Design
TIDA-00281
Overview
TIDA-00281 is a 3-phase brushless DC (BLDC) motor drive designed to operate in 48-V automotive applications. The board is designed to drive motors in the 1-kW range and can handle currents up to 30 A. The design includes analog circuits working in conjunction with a C2000 LaunchPad to spin a 3-phase BLDC motor without the need for position feedback from hall effect sensors or quadrature encoder.
Features
- Speed control of 3-phase BLDC motors with no position sensors needed
- Phase voltage and current sensing scaled and filtered feedback for control of the 3-phase power
- Operates over a wide range of voltages from the 48-V battery system
- Reverse polarity protection on 12-V battery
Automotive
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
