The provided AC Drives application has enhanced drastically in HVAC applications. These are now typically used to tower fans, air handlers, chillers and pumps. They are integrated with a rectifier that is utilized to transform incoming AC energy to DC power. A single rectifier will permit power to go through only when the current is positive. Whereas the second rectifier will permit power to go through when the current is negative. Therefore, two rectifiers are needed in our AC Drives for every phase of power. These are delivered to the customers in varied designs, specifications and sizes to suit varied electrical applications.
