Abstract
A non-contact type power receiver may includes: a plurality of power receiving coils receiving power in a non-contact manner; a plurality of rectifying units switching to rectify the power received from the plurality of power receiving coils; and a control unit controlling the switching by the plurality of rectifying units to control respective levels of the power rectified by the plurality of rectifying units.
Claims10
A non-contact type power receiver comprising:
- a plurality of power receiving coils receiving power in a non-contact manner;
- a plurality of rectifying units switching to rectify the power received from the plurality of power receiving coils;
- and
- a control unit controlling the switching by the plurality of rectifying units to control respective levels of the power rectified by the plurality of rectifying units,
- wherein each of the plurality of rectifying units has a full bridge structure including first and second switches forming one leg and third and fourth switches forming the other leg connected to the one leg in parallel, and
- wherein the control unit compares a carrier signal having a frequency higher than a transmission frequency of the power transmitted to the plurality of power receiving coils with a current reference signal of the received power, and controls the switching of the first and second switches using a pulse width modulation (PWM) scheme, depending on a comparison result.
