ACTIVE CONSTRAINED LAYER DAMPING OF CLAMPED-CLAMPED PLATE VIBRATIONS

Journal of Sound and Vibration, 2001
Abstract Surface damping treatments are often effective at suppressing higher frequency vibrations in thin-walled structures such as beams, plates and shells. However, the effective suppression of lower frequency modes usually requires the addition of an active vibration control scheme to augment the passive treatment.

Actively clamped bidirectional flyback converter

IEEE Transactions on Industrial Electronics, 2000
An actively clamped bidirectional flyback converter is proposed. The converter's operation is examined in detail. All switches in the converter have zero-voltage-switching characteristics. A low-frequency behavior model and small-signal transfer functions are derived. It is found that the flow of current is directly under the control of the duty cycle,
