- The apace vector PWM has the character of wide linear range, little higher harmonic and easy digital realization, so it is being widely used in PMSM driver system.
- For the damage of electric network higher harmonic,analyze the cause of higher harmonic measures and propose control higher harmonic measures.
- To reject higher harmonic produced in process of temperature adjusting,a zero-crossing triggering technic is put forward.
- Over 35 years ago, I began developing a new tonal vocabulary for the piano that allows the higher harmonic overtones to speak as eloquently as the notes themselves.
- With the increase of the laser intensity, HR lines only appeared as the background of high harmonic generation (HHG) due to its weak intensity.
- The occurring of higher harmonic is introduced,its harm to power system is analyzed and the measures to suppress the harmonic of power system are proposed.
