The objective of this paper is to model and simulate a three-phase Voltage Source Pulse Width Modulation (PWM) Rectifier Based on Direct Current Control feeding an indirect vector controlled Induction Motor Drive (VCIM) and 3-Level SVM based PMSM Drive. Based on the mathematical model of PWM rectifier, the dual close loop engineering design with decoupled feed-forward control is applied in the three...
Permanent-magnet synchronous motors (PMSMs) with a sinusoidal back EMF are widely used in domestic appliances for reduction of acoustic noises and energy consumption. PMSMs are generally controlled with a sinusoidal waveform current. Typically, PMSMs are controlled by vector controlled sinusoidal drives, which require powerful computational resources. Hence, simpler sinusoidal wave drives such as...
A method of sensorless vector control with unity power factor for surface mounted permanent magnet synchronous motor (SPMSM) is presented. The method can realize the motor control of unity power factor under the rated speed, and the motor can also work normally under high speed by way of field weakening. Comparing with the vector control of the statorpsilas magnetic force plumbs with the permanent...
Standard drive systems are usually connected to the utility grid using six pulse diode rectifiers. This kind of the rectifiers has many disadvantages, for example non sinusoidal supply currents, non unity power factor, and the DC-link voltage cannot be controlled. To overcome these disadvantages the use of controlled PWM rectifiers seems to be appropriate. There are many control schemes proposed for...
