| Abstract |
With new EMI standards new converter structures and control methods are necessary. In the past usually
phase control was the appropriate method for the control of simple ac loads (e.g. lamps). The disadvantage of phase control is generation of additional reactive power and of harmonics in the mains. The circuit proposed in this paper is able to reduce the harmonics in the mains significantly. Reactive power due to control is avoided. A enhanced version
additionally avoids significant harmonics at the load side. |
