Based on the application of Switched Reluctance Motor, select asymmetrical half bridge topology structure, selection of four parallel MOSFETs as power switching devices to construct a low cost power converter. The main hardware parameters which may cause the uneven flow are studied. Further through the software optimization control, the current sharing results are corrected. That in turns chopper...
The Ni-W-P/Ni-B duplex coatings were deposited on AZ91D magnesium alloy by electroless plating and evaluating their structure, morphology and corrosion resistance. The duplex coatings were deposited in dual baths (alkaline hypophosphite- and borohydride-reduced electroless nickel baths). The coatings were amorphous in as-plated condition. Upon heat-treatment, they were crystallized and produced nickel...
