| Abstract: | Three-level PWM switching power amplifier is a new type of amplifier which is suitable for magnetic bearing systems. A circuit diagram was designed based on FPGA according to the working principle of the amplifier described in the paper. Some basic principles, components and requirements of the circuit are introduced. The result of experiments proved that this type of amplifier has good dynamic characteristics within the frequency range required by the magnetic bearing system. |
