MIMO sequence impedance modeling and stability assessment for grid-connected dual-PWM adjustable speed drives

The dc link of dual pulse width modulation (PWM) adjustable speed drives (ASDs) is coupled with inverter-motor-drive systems (IMDs) and grid-side converters, forming a multi-coupled system that complicates grid stability analysis beyond that of traditional inverters. By identifying a previously unex...
