Abstract: Faster and precise solution of inverse Park transformation is required to reach the
optimal efficiency and steadiness of the servo drive. The main problem in presenting
such solution lies in completing the transformation within a limited clock cycles as well
as execution time. One of the options could be to implement the overall transformation
algorithm into field programmable gate array (FPGA) for reducing the execution time
significantly. This research presents a fully integrated solution of inverse Park
transformation by incorporating Coordinate Rotation Digital Computer (CORDIC),
Arithmetic and Phase-locked Loop (PLL) modules. The result shows that the proposed
FPGA performance is required only 68ns of execution time for operating frequency of
30 MHz and accuracy of 99.9%, which is the lowest computational cycle for the era.
