A non-contact type power receiving apparatus, of which a voltage level of output power varies depending on a rated voltage of a battery, includes: a power receiving coil unit receiving a power in a non-contact scheme; a rectifying/multiplying unit rectifying the received power depending on controlling thereof and selectively multiplying a voltage level of the rectified power; and a controller selectively controlling a rectifying operation or a multiplying operation of the rectifying/multiplying unit to be performed depending on a selection signal.

Non-contact type power receiving apparatus

A wireless power receiver according to an exemplary embodiment in the present disclosure may include a resonant tank receiving a power signal and varying a resonant frequency in response to a control signal; and a determining unit determining a wireless power transmission mode on the basis of the power signal and outputting the control signal depending on a determination result.

Wireless power receiver and method for controlling the same

A direct current (DC) power supply for varying an output voltage according to a load current variation is disclosed. The DC power supply includes an alternating current (AC)/DC conversion unit converting commercial AC power into DC power, a DC/DC conversion unit converting a voltage level of the DC power and outputting output power, and a control unit controlling conversion of the voltage level of the fed-back DC power according to a variation in a load current of the output power from the DC/DC conversion unit.
