  ripple
We deal with the maximum Gibbs ripple of the sampling wavelet series of a discontinuous function f at a point t ∈R, for all possible values of a satisfyingf(t)=αf(t-0)+(1-a)f(t+0).
      
However, a ripple current occurs in the inactive phase due to the diode freewheeling during the non-commutation period in the traditional pulse width modulation (PWM) methods, which aggravates the torque ripples.
      
As a result, the torque ripple is suppressed using the proposed method.
      
Thrust ripple optimization and experiment for a permanent magnet linear synchronous motor
      
Thrust ripple such as end force, slot force and normal force are key factors that affect the properties of permanent magnet linear synchronous motors (PMLSM).

  the ripple
In a multichannel X-ray detector based on epitaxial GaAs structures, a low-pass filter was used to reduce the ripple at the amplifier output.
      
The output voltage is smoothly regulated from 0.5 to 3 kV, the load current is 0-2 mA, and the ripple factor is 0.008%.
      
It is shown that, in a cylindrical plasma in a constant, periodically rippled, axial magnetic field, the structure of Alfvén resonance and the absorption of RF power can strongly depend on the ripple amplitude.
      
It is found that the high-frequency power absorbed near the local resonance is proportional to the square of the ripple amplitude of the external magnetic field.
      
It is shown that the ripple-induced correction to the eigenfrequency of the waves is a second-order quantity.
