<P>PROBLEM TO BE SOLVED: To provide a system for contactless energy transmission, which can be used in efficient and various devices. <P>SOLUTION: A contactless power supply has a tank circuit that is operated by an inverter and can dynamically be constituted. The contactless power supply is inductively coupled to one or above loads. The inverter is connected to a DC power supply. When the load is added to the system or the load is removed from the system, the contactless power supply can change a resonance frequency of the tank circuit, a frequency of the inverter, a duty cycle of the inverter or rail voltage of the DC power supply. <P>COPYRIGHT: (C)2007,JPO&INPIT |
