Soft-start of High-power Medium-frequency Transformer made by Amorphous Alloy
Yao Cheng · IEEE Transactions on Power Electronics · 2003
High power medium frequency transformer made by amorphous alloy has more excellences than sillicon steel,such as low wastage,high efficiency,small volume,and high stability,but the problem of magnetism saturation appers when starting this kind of transformer directly and induces over current.The power electronic components may be damaged consequently,so it must be started softly.The principle of soft starting and strategy of control based o n intel 80C196KC are given, which have been applied in industrial production and proved to be satisfied.
