VFD Power Systems

IDS understands VFDs, having serviced and integrated drives for over 40 years. We design and package drive systems to stand up to demanding oilfield and marine environments, and yet deliver the best control possible. We also provide training and technical support to assure successful startup and reliable operation.

VFDs are recognized as the preferred method of control for both offshore and land rigs. IDS proudly integrates Vacon® inverters to offer the oilfield’s most compact and robust drive system.

Our VFD systems power rig equipment including drawworks, top drive, rotary table and mud pumps. Common DC bus architecture provides a measure of redundancy and allows power to be shared between motoring and regenerating loads, improving overall system efficiency.

Regenerated power not consumed by other loads is routed to a dynamic breaking circuit that is part of every VFD power package. All VFDs and the dynamic braking system are fully controlled and monitored by the IDS control system.

Let our sales and engineering teams discuss your exact requirements, so we can provide a power system specifically suited to your rig.
