Based on the analysis of the basic principle of specific harmonic elimination technology, a kind of specific harmonic elimination frequency converter is designed and its voltage-variable frequency conversion circuit and protection circuit are deeply studied. The experimental results show that the frequency converter has many advantages, such as eliminating the number of harmonics and keeping the amplitude of the residual harmonic components small, which makes the motor less heat loss
