| Abstract |
The use of active PFC-circuits should not only be discussed under the aspect of fulfilling normative
requirements; it also could help to increase the power of electrical machines in the fieldweakeningrange
and to solve the problem of high harmonic currents in the neutral-line, when using a lot of units
with single-phase rectifiers. The cost for power-supply installations can be reduced due to the
improved power factor.
The increased utilization of electrical machines can be reached with active power factor correction
circuits based on the boost principle; some known solutions either for single phase and for three phase
connection are presented and their specific advantages discussed.
Future improvements could be the realised with SiC-diodes and synchronous rectifying. |
