| Abstract |
Unipolar power converters allow to reduce cost and circuital complexity of DC brushless motor drives
by reducing the number of required power switches per phase. A new converter topology is presented
that allows to improve the power factor of unipolar DC Brushless Motor drives, aimed to equip low
cost variable speed drives. It features an unipolar topology with a modified C-dump energy recovery
stage, that allows to perform an active power factor control. According to the presented approach no
additional power factor control stages are necessary to comply with power quality requirements.
Moreover, the proposed converter topology featuring only low side switches, allows to simplify the
switch control circuits and opens the perspective of integrate all the converter on a single chip
exploiting smart power technologies. |
