output ripple, usually requires a larger output of electrolytic capacitors (220uF). Secondary structure has the advantage of the output ripple is small, so you can remove the large electrolytic output capacitors, and replaced by smaller-capacity ceramic capacitors or film capacitors. However, the efficiency of the secondary structure at the expense of the general overall efficiency can be above 80%, while a structure is usually more than 90% can be achieved. In addition, the secondary structure
