| Abstract: | Aiming at the shortage of linear power amplifier and two-level PWM switching power amplifier,a kind of three-level PWM switching power amplifier in magnetic suspension thrust bearings was proposed and its basic principle was described. A novel three-level PWM switching power amplifier was designed. The analysis shows that compared with two-level PWM switching power amplifier,the threelevel switching power amplifier has characteristics of lower current ripple,less power loss,stronger anti-electromagnetic int... |
