一种用于永磁同步电机的无缓冲固态分接开关

A stator winding tap changer has been studied for a permanent magnet synchronous motor (PMSM) drive for speeds exceeding the base speed range. At low speeds, all stator windings are configured to fulfill the high output torque; at high speeds, a portion of the stator windings are configured to relieve the burden of the stator winding turns, i.e., large inductive impedance, back electromotive force...
