This regenerative converter is capable of continuous operation and a power supply rate of nearly 1.0, while suppressing current distortion factor using our proprietary switching method and being less susceptible to the effects of supply voltage distortion. This meets the demand for clean power supplies.
Contributes to clean power sources by suppressing overall current distortion at the rated load to 5% or less and conforming to guidelines for harmonic suppression measures.
The value of the operation power factor is 99% or more at the rated load and 95% or more at 30% or more of the rated load. This enables the equipment to be built smaller than before.
Delivers the capabilities of a regenerative converter for AC drive, whether used alone or with multiple units. The operation of multiple units is particularly advantageous because power regeneration has the added effect of power cancelation and high AC drive efficiency, and combining these with a high power rate results in a further reduction in equipment load.
