Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

In the PFC converter design must carefully deal with the hard switching losses due to the recovery current of boost diode. There are two approaches had proposed to solve the hard switching losses issue. One is passive soft switching method and the other is active soft switching method. Practically, the passive soft switching method has been used more widely in industry, because of it has simple, low cost, and reliable. Although, the passive soft switching method has more merits but it still exists some drawbacks that need to be improved. This thesis proposes the improved zero current switching method not only to solve the hard switching issue but also to improve drawbacks of the passive soft switching method. Especially, the saturable core (Amorphous core) and a branch circuit are proposed to substitute the fixed inductor in ZCS circuit. This proposal optimizes the passive soft switching circuit and improves many drawbacks. 
In this thesis, besides the principle of operation is introduced in detail, the experimental results of the real implementation is compared with the hard switching PFC converter as well as others passive soft switching. According to experimental results, this proposed improved zero current switching method is proved feasible, and also improves the most of drawbacks of passive soft switching methods.
