| Abstract: | In order to study the performance of three-phase VSR,three-phase PWM rectifier control system based on TMS28346 is designed.For convenience of control,two-phase rotate reference frame is constituted and also vector con-trol technology is introduced.A control strategy using inner current loop and outer voltage loop is proposed to realize DC voltage control and independent control.Four typical running modes of three-phase VSR is analyzed,the relation-ships among modulation ratio,DC bus voltage,AC voltage and ... |
