A Space Vector based Pulse Width Modulation

\r\ncontrol technique for the three-phase PWM converter is proposed in

\r\nthis paper. The proposed control scheme is based on a synchronous

\r\nreference frame model. High performance and efficiency is obtained

\r\nwith regards to the DC bus voltage and the power factor

\r\nconsiderations of the PWM rectifier thus leading to low losses.

\r\nMATLAB\/SIMULINK are used as a platform for the simulations and

\r\na SIMULINK model is presented in the paper. The results show that

\r\nthe proposed model demonstrates better performance and properties

\r\ncompared to the traditional SPWM method and the method improves

\r\nthe dynamic performance of the closed loop drastically.

\r\nFor the Space Vector based Pulse Width Modulation, Sine signal

\r\nis the reference waveform and triangle waveform is the carrier

\r\nwaveform. When the value sine signal is large than triangle signal,

\r\nthe pulse will start produce to high. And then when the triangular

\r\nsignals higher than sine signal, the pulse will come to low. SPWM

\r\noutput will changed by changing the value of the modulation index

\r\nand frequency used in this system to produce more pulse width. The

\r\nmore pulse width produced, the output voltage will have lower

\r\nharmonics contents and the resolution increase.<\/p>\r\n","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 93, 2014"}
