Abstract
A system is disclosed that controls the power flow to Linear Synchronous Motor (LSM) stators for a vehicle transport system. This invention allows multiple vehicles to operate in close proximity in a guideway without requiring an excessive number of separate controllers. It can be used in conjunction with schemes now in use and is particularly useful in elevator hoistways or for automated people movers near stations.
