Drive systems are more commonly being configured with a common DC bus; for good reason. Common DC bus configurations create advantages including cost savings, greater efficiency, and a more versatile system design.
There are multiple methods of creating a common bus systems. One method is the use of a rectifier that supplies DC power to all of the drives instead of individual rectifiers for each drive. Bonitron has 3 solutions for this method:
In most common DC bus applications, costs are lowered due to sharing of power among the drives. For example, not all drives may be motoring at the same time, which will reduce the need for excess braking, power supply, or other such components.
Another alternative is the use of steering or isolation diodes. Bonitron has diodes that allow your drives to share regenerative energy on a common bus (M3345CBM), or isolate the drives separately (M3345D).
Bonitron common DC bus configuration accessories work with drive systems with DC bus connections.
