Four Quadrants or regenrative

04/20/2010 7:16 AM

I am sorry for asking a basic question as i don't have sufficient knowledge on this topic. Please explain;

If a drive has 12 thyristors, is it a 4 quadrants or REGENERATIVE drive?

Any useful link on this topic?

A 4 quadrant drive provides full forward and reverse speed control and braking. Regenerative means the braking energy is fed back into the power source as opposed to being dumped as heat into a (dynamic) braking resistor. All the 4 quadrant drives I have used are also regenerative drives, so the terms are commonly used together.
