Abstract：When the permanent magnet assisted synchronous reluctance motor（PMaSynRM）runs at highspeed with flux-weakening control，the DC bus voltage utilization is not high，and the efficiency and torque output capacity of the motor are low. Therefore，a flux-weakening control strategy of permanent magnet assistedsynchr...

Abstract：Under digital control，the inner current loop of the LC-type inverter is affected by the control delay，which leads to the weakening of its active damping effect. Increasing the sampling control frequency can effectivelyreduce the negative influence of digital control delay. Furthermore，in order to suppress t...
