Wireless Power Transfer: Critical Review of Related Standards

Wireless power transfer system (WPT) turned to be a reliable and an appropriate strategy, which found many applications. However, there is a growing concern about two safety issues. The first one is linked to the human exposure to electromagnetic fields (EMFs) that may cause potential health hazards. The second issue is the electromagnetic compatibility (EMC), where WPT systems may cause disturbance to electrical circuits. With the rapid development of WPT systems including the wide range of frequency and power, many leading countries in WPT industry have set many standards and regulations for safety usage of WPT. However, due to the complexity and variety of these standards, it is usually difficult to follow for both researchers and electrical engineers. This paper aims to provide a review for the recent standards and regulations concerning WPT industry and its applications. Therefore, a simple classification with a comprehensive comparison is presented.
