Design :
The AC mains powers the input winding which is widely separated physically form the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits on intrinsic energy storage characteristic and this energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field which is indirectly excited from the input windings.
 

• No Semiconductors or moving parts used, hence very high reliability
• No feedback control used
• Intrinsic current limiting and short circuit protection
• Output voltage correction within 1/2 Cycle (10 milliseconds) from no load to full load for specified load & line variation.
• Short term over load capacity
• Energy storage for line loss upto to 3 milli seconds at typical load.
• Higher input voltage control range, for loads less than rated load.
• Very high line transient/spike rejection capability and excellent isolation characteristic.
• Output floating (Optional)
