摘　　要：根据三态开关功放理论,利用SG3524,IR2110等集成芯片设计了磁轴承三态PWM开关功率放大器。理论分析和试验表明,该功率放大器具有电流纹波小、电磁干扰小、效率高等优点。A tri-state PWM power amplifier is designed for Magnetic Bearing. Integrated chips SG3524, IR2110 are used for it. Theory analysis and experiments prove that such tri-state power amplifier has a series of advantages such as： little current wave, slight electromagnetic interference, high efficiency and so on.
