Abstract

A non-contact type power transceiving apparatus may include: a non-contact type power transmitting apparatus adjusting bias power setting a level of transmission power based on a request and transmitting one of a first power and a second power having a power level higher than that of the first power in a non-contact scheme; and a non-contact type power receiving apparatus requesting one of the first power and the second power from the non-contact type power transmitting apparatus and varying a set temperature level determining an abnormal state based on the requested power.

Claims

1. A non-contact type power receiving apparatus, comprising:

a rectifying unit rectifying received power;

a converting unit converting the rectified power into charging power and transferring the charging power to a load;

a detecting unit detecting physical characteristics occurring at the time of power reception; and

a controlling unit requesting a first power or a second power having a power level higher than that of the first power based on a user selection and varying a set level determining an abnormal state based on the requested power.

2. The non-contact type power receiving apparatus of claim 1, wherein the controlling unit varies a set temperature level based on the requested power.

3. The non-contact type power receiving apparatus of claim 1, further comprising a power receiving impedance matching unit varying power receiving impedance based on a power request from the controlling unit.

4. The non-contact type power receiving apparatus of claim 1, wherein the controlling unit controls an operation of at least one of the rectifying unit and the converting unit and varies impedance detected from a power transmitting side to request necessary power.

5. The non-contact type power receiving apparatus of claim 1, further comprising a communication unit transferring a power request from the controlling unit based on a user selection to a power transmitting side.
