Abstract

Electrical control system plays a decisive role in the running performance for a permanent magnet biased magnetic bearing. Power amplifier, as a part of the electronic control system, its performance directly affects the suspension system. Therefore, the amplifier design is an important part of the system. A three-level switching power amplifier is presented in this paper, which uses a three-level PWM switching scheme. The implementation of the hardware and control strategy is explained in detail. Simulation and experiment results show that with the full-bridge three-level PWM switching power amplifier, it can provide bidirectional current and meet the needs of current control of magnetic bearings. Thus it may improve the DC bus voltage to increase the dynamic circuit performance while reducing current ripple.
