N2 - For a permanent magnet electrodynamic shaker (PMEDS), an LC filter is frequently connected in series to filter out the high-frequency voltage to avoid high-frequency harmonic acceleration of the PMEDS table. This paper use a simple current control loop to avoid high-frequency harmonic acceleration instead of an LC filter which may have large size and heavy weight in high-power applications. A cascade H-bridge inverter is used in this paper to lower the output voltage harmonics and current ripple. According to the provided simulated and experimental results, it can be found that the proposed current control can improve the acceleration of the PMEDS.
