Abstract

Switching power amplifier is a key component of the actuator of active magnetic bearing, and its reliability has an important impact on the performance of magnetic bearing system. This paper analyzes the topologies of switching power amplifier of active magnetic bearing. In the case of different coil pair arrangements and bias current distributions, comprehensive evaluation on different topologies of switching power amplifier is introduced. The valuation has a guiding role in the design of switching power amplifier of active magnetic bearing.
