  • Publication number: 20080151585
    Abstract: A converter control apparatus comprises menas (14) (15) (17) for detecting output powers of a plurality of converters (100) connected in parallel to a load; an arithmetic circuit (19) for calculating an average output power of the converters on the basis of the detected output powers, and an output power control circuit (18) for controlling the output power of each converter such that it is equal to the average output power. This prevents non-uniformity from occurring in supplying the power from each converter to the load and hence prevents any of the converters from exhibiting an overload condition beyond a rating range.

  • Publication number: 20080055181
    Abstract: In resonant elements 102 to 105 constituting a resonant circuit, an uncontrolled cross coupling which exists between two resonant elements is controlled by using a coupling element 106 which is newly arranged between the resonant elements, whereby it is possible to create a state where two resonant elements are not coupled with each other or a state where the amount of the coupling is reduced, which states are difficult to be realized on a plane. As a result, it is possible to improve characteristics of a planar filter.
