摘要: In this paper several new techniques to reject dc-link voltage ripple in PWM inverters are examined detail. It is demonstrated how continuous elimination of harmonics achieved at the inverter output while simultaneously rejecting ripple. Thus with proposed it possible guarantee high quality even substantial low frequency on dc-link. A thorough modeling these along tradeoffs involved acquiring immunity illustrated Potential applications fixed and variable for power supplies ac motor drives which experience such as when fed from a weak system frequently unbalanced. Suitable design equations digital implementation procedure technique described Finally, selected results verified experimentally laboratory inverter.
