390 Introduction to Electrical Power and Power Electronics
Currents source inverter (CSI): it maintains a constant current on the inverter
input side by using a large inductor. If the dc side inductor L
dc
in Figure
14.13 were made innitely large, it would become a CSI.
Commutation: it refers to turning off one thyristor and shifting the current to
another. It can be natural or forced by additional circuits.
Flyback converter: the dc–dc converter in which the stored magnetic energy
in one inductor coil jumps to another inductor coil—ying from the source
side to the load side on the back—when the switch opens. The magnetically
coupled yback inductor coils essentially form an air-core transformer with
turn ratio N
