Moldaschl, Jan
Impulsní výkonové síťové nabíjecí a napájecí zdroje

A massive using of switched mode power supplies causes a high harmonic pollution of the line current. The distortion is significant due to a non-linear behaviour of the rectifying diodes and bulky input capacitor of SMPSs. The behaviour causes short spikes of the line current,...
