Research on the use of the card-type non-contact power-supply system as a powering device for the card-type portable equipment is continuing. We have developed a new transmitting coil unit that uses a Co-based amorphous ribbon and ferrite magnetic cores. This new coil unit is thin yet very flexible and high magnetic coupling factor. The coil unit has allowed us to use a thinner card. The new unit puts on two ferrite cores above stacked three 25-μm-thick ribbons, having more superior electrical characteristics.
