Modeling and Design Optimization of Contactless Sliding Transformer System for ropeless elevators
In this paper,two novel topological structures of sliding transformer with ferromagnetic core applied in the Contactless Electrical Power Transmission(CEPT) system used for the ropeless elevator driven by moving-coil type Permanent Magnet Synchronous Linear Motor (PMLSM) have been proposed,and the magnetic field distribution of them have been calculated and analyzed by the finite element method(FEM).According to the analysis results,comparing with the traditional E-E topology sliding transformer,much higher coupling coefficients of sliding transformers with proposed topologies have been obtained.Then,based on the magnetic distribution and the circuit model of system,the compensation capacitances have been calculated considering supply frequency and load conditions.Finally,the load characteristic of the system with compensation is also obtained by FEM.
