Sentence examples for low frequency ripple from inspiring English sources

The low frequency ripple mitigation is based on active control.

This paper also proposes a novel controller for low frequency ripple current suppressing applied on the converter.

The seafloor is composed with two sand ripples phenomena at different frequencies and different sediments (VeryFineSand for the high frequency ripples and VeryCoarseSand for the low frequency ripples).

Three separate spacecraft, flying millions of kilometers apart from each other at the vertices of a giant triangle, would precisely measure their mutual separations using sensitive lasers, and thus be capable of detecting low-frequency ripples in spacetime.

Furthermore, a novel PCS controller is presented, which succeeds in suppressing the low frequency current ripple, controlling the dc link voltage and inverter output current.

For the improved three-level (TL) buck direct current-direct current (DC-DC) switching converter which is a high-order, discrete, non-linear, and time-variant dynamic system, the work multi-modalities and principle are analyzed, and the state space equation model is established by introducing the switch cycle averaging operator under low-frequency, small ripple, and small-signal assumption.

The results show that unlike vertical low frequency (lower than 20 Hz) vibration excited by road roughness, broadband torque ripple will arouse horizontal high frequency (50 100 Hz) vibration of electric wheel system due to participation of the three aforementioned modes.

The ripple mitigation performances are evaluated by indicators that are defined to measure the mitigation ratio of the low frequency harmonics.

Electrical power is low frequency -- 60 hertz or less.

As it happens, it is considerably harder to feel vibrations of high frequency than those of low frequency.

No, not that low frequency.
