中文摘要	Since a power amplifier acts as an actuator in the active magnetic bearing (AMB) system, it can affect the system performance directly. In order to improve AMB system performance, it must meet the indices of the current response velocity, force response velocity, the maximum synchronous frequency vibration magnitude permitted and the unbalance control value. As an example of an AMB system with minimal pulse width switch power amplifier, from the point of the frequency domain, some key parameters of amplifier are designed after the analysis of actual working requirement. By designing some main coefficients of the power amplifier reasonably, it keeps the system performance, and also reduces the manufacture cost. After some theory analysis and simulation, some examples with the above methods are given. This paper presents some valuable ideas on how to design an amplifier of an actual AMB's system are presented.
