Chang Sung Corp, the leader in powder core technology has expanded it’s toroid line to larger sizes. For Alternative Energy the preferred material for these toroids is the CSC MegaFlux material.
As a material review, Chang Sung was the first powder core company to introduce a Silicon-Steel powder for, essentially replacing Silicon-steel laminations in transformers. The advantage of the MegaFlux is lower core losses and a higher operating frequency. The MegaFlux can also be pressed is varying shapes, the most common are the Toroid, EE core, and Blocks.
Chang Sung has recently introduced the toroids in the sizes from four (4) inch to six (6) inch. These toroids are summarized in the following table.
The most common Value of the MegaFlux for alternative energy is the 26 perm material. The graph below is the Graph showing the DC Flux for the 26 Perm MegaFlux material.
Generic Application – Boost Reactor Transformers ( Step-up) and Inverter Reactor
