Abstract :
This paper analyses the influence of the modulation technique on the size of the grid EMI filter inductor in a full bridge converter for photovoltaic systems. Additionally, the use of an alternative modulation technique is proposed which exhibits the best compromise concerning efficiency, current quality and EMI filter size.
