Abstract In the electric traction transmission system, subject to the maximum switching frequency and output voltage and current harmonic performance, a special optimized pulse width modulation strategy is generally required. The selected harmonic elimination PWM eliminates the lower-order harmonics so the interference of motor torque will decrease. In this paper, the basic principles of SHE-PWM (selected harmonic elimination PWM) technology are studied; meanwhile, the method of using MATLAB to calculate switching angle is introduced. Then, the limitation of SHE-PWM based on DSP and the advantage based on FPGA are analyzed. Besides, the frequency conversion speed control system based on the SHE-PWM algorithm is completed through the FPGA, and the experimental results verify the theoretical analysis of SHE-PWM.
