BATTERY-INCORPORATING APPLIANCE AND CHARGING STAND, AND BATTERY-INCORPORATING APPLIANCE

摘要

[Problem] While minimizing generation of heat by a rectifying circuit, to effectively prevent failure caused by abnormality of withstand voltage of the rectifying element employed in the rectifying circuit, by adopting an extremely simple circuit layout and using an inexpensive semiconductor switching element. [Solution] A battery-incorporating appliance and a charging stand comprise: a charging stand (10) equipped with a power delivery coil (11), and a battery-incorporating appliance (50) that incorporates a power-receiving coil (51) that is electromagnetically coupled with this power delivery coil (11). An incorporated battery (52) of the battery-incorporating appliance (50) is charged with power delivered to the power-receiving coil (51) from the power delivery coil (11). The battery-incorporating appliance (50) is equipped with: a full wave rectifying circuit (53) that rectifies AC that is induced in the power-receiving coil (51); a charging circuit (54) that charges the incorporated battery (52) of the battery-incorporating appliance (50) with the output of this full wave rectifying circuit (53); and a short-circuiting circuit (70) comprising a semiconductor switching element (71) that protects the semiconductor elements of the full wave rectifying circuit (53) by short-circuiting the output side of the full wave rectifying circuit (53) in the event of abnormality.
