Wall-plug efficiency analysis of semi-active piezoelectric shunt damping systems

Original language description

Analysis of the wall-plug efficiency, i.e. the ratio of reflected and absorbed acoustic power over the total electric input power,of semi-active vibration control devices based on the principle of the active piezoelectric shunt damping is presented.The vibration suppression element in the considered vibration control device consists of a piezoelectric actuator, which is connected to the active synthetic impedance shunt circuit that emulates a negative capacitance.Two types of power amplifiers can be used in the implementation of the synthetic impedance:linear (class B, AB) and switching (class D).Using both implementations of the synthetic impedance, a decrease in the transmissibility of vibration by about 30?dB in narrow frequency ranges around 500?Hz, 700?Hz, 900?Hz, and 1.1?kHz has been achieved.The mechanical input power transferred from the source of vibration to the vibration control system, the electric power flow from the piezoelectric actuator to the active shunt impedance
