Usually, a boost converter is used to link source voltage and inverter in ac motor driving system. In this paper, a boost converter control system is designed to offer stable dc link voltage and assure the inverter could provide regulated sinusoidal power to ac motor under flexible input voltages (rectifier utility power or battery packs). The mathematic model of the boost converter based on PWM three-terminal...
This paper presents a novel DC link voltage feedforward control to improve the electric drive system tolerance capability to the dc link voltage sag. A uniform mathematic model, comprising the battery packs, voltage source inverter (VSI), permanent magnet synchronous motor (PMSM) is built up in the d-q rotating coordinates rather in three-phase stationary coordinates. In order to study the influence...
