Development of Double Suspension Frame Electromagnetic Permanent Magnet Hybrid Maglev Controller
摘要
In this paper, the electromagnetic permanent magnet hybrid levitation model was introduced, and the H-type four-quadrant hard switching chopping technology scheme was applied, and on the basis of analyzing the circuit principle and structure of the normally guided suspension controller chassis, the dual-suspension electromagnetic permanent magnet hybrid suspension controller was successfully developed to complete the engineering mass production application. The electrical performance test results show that the suspension controller fully meets the technical requirements, and has the advantages of reasonable structure layout and strong anti-electromagnetic interference ability.
