PowerFlex 700H and 700S Drives - Frame 13 Procedures

Frame 13 Drive
Configurations

Frame 13 drives consist of a converter section and an inverter section, as shown
here.

For frame 13 drives, the converter
section has two or three rectifier
sections depending on the power
rating, while the inverter section
always has three power sections.
The converter converts ac (fixed 50
/ 60 Hz) to dc voltage. The inverter
section inverts dc to variable ac
frequency.
