A Matrix converter-interfaced PM Generator System with Active Filtering Capabilities

Abstract

In  this  paper  is  presented  a  matrix  converter- interfaced Permanent Magnet (PM) generator system which can provide  shunt  active  filtering  in  addition  to  converting  and transferring energy. The modulation technique is the simple and well-known  indirect  space  vector  modulation.  The  filtering current  injected  by  the  matrix  converter  and  the  input  filter capacitor   voltage   are   controlled   by   cascaded   proportional control   loops.   Results   showing   that   the   matrix   converter successfully    provides    active    power    filtering    are    given. Simulations  also  indicate  that  the  filtering  capability  of  the system   depends   on   the   generator   side   power   factor.   An explanation to this effect is given.
