To provide a method and system for non-contact compact supply of power, wherein the power generated by converting kinetic energy to electric energy is accumulated and then is transmitted non-contact to a load device of a portable equipment.
A card-type power supply equipment 1 is provided with a power generator 3 due to kinetic energy which generates power by converting kinetic energy to electric energy, a rectifier circuit 4 for rectifying power, a secondary battery or electrical double layer capacitor 5 for storing power, a load device detector 6 for receiving signals from the load device 2 non-contact, a voltage controlling circuit 7 for transforming voltage, a DC/AC converter circuit 8 for converting DC to AC, and a transmission coil 9 for supplying power non- contact to the load device 2. The load device 2 is provided with a load device existence announciator 10 for transmitting non-contact the existence of the load device 2 to the load device detector 6, a power receiving coil 11 for receiving power from the transmission coil 9 non-contact, a rectifying and smoothing circuit 12 for rectifying and smoothing power, and an electronic circuit 13 which is a load section.
