| Summary: | 碩士 === 逢甲大學 === 資訊電機工程碩士在職專班 === 99 === Recently, various types of consumer electronic products are appeared on the
market by the technological improvement. These consumer electronic products are
required to maintain its power for general operations. The power sources are
mostly from secondary batteries to keep working. Although secondary battery can
be reduced to the environmental pollution with the characteristic of repeated use,
the various electronics companies are not designed to the same specifications, so
that different manufacturers have different cable charger. When these electronic
products are broken, these chargers will not be used any more, and that will results
in many unused charger. The wasted charger is not only higher cost to a product,
but also not environmentally friendly to the Earth.
At present, people have wireless charging applications, such as PHS mobile
phone charger and electric toothbrush charger. These methods avoid that the
charging cable contacts the power terminal and have more integrated sense to a
mobile device. The charger will waste the power when the product is not in use but
the charger is in working condition if the charging is completed. That people have
to manually disconnect the AC power also caused inconvenience.
This thesis provides a smart wireless charger which can charge different
types of handheld devices and go into sleep mode to save power consumption after
the charging process is completed to meet the current world trends is to reduced
carbon and to save energies.
