摘要: The analysis of an unbalanced PWM AC-to-DC converter by the transfer function approach is presented. proposed procedure provides for closed-form assessment all harmonics generated under operating conditions suitably decomposing into positive and negative sequence components. A three-phase with programmed patterns fully analyzed. distortion at output evaluated unbalance. increase in unbalance attributed primarily to appearance a second-harmonic component. An algorithm selectively cancelling component Suitable implementation techniques are also discussed. >
