Method and apparatus for eliminating harmonic components and obtaining a uniform power factor in alternating current-direct current and direct current-alternating current converters

The present patent application relates to a method and equipment for eliminating harmonics based on two complementary techniques, namely the elimination of harmonics by selective harmonic elimination pulse-width modulation in conjunction with the multiple-wiring transformer. The association of these two resources is capable of reducing the harmonic distortion of currents to extremely low values, providing a truly unitary power factor. ...

System and method for authentication of things

An authentication of things (aot) system includes a cloud server configured to control a cloud domain connected with a plurality of devices, a home server configured to control a home server connected with a plurality of devices, a first device corresponding to a new device, and a second device of a root user connected with the home domain while authentication is completed in the home server. In this case, the first device loads cryptographic material of the cloud server from the cloud server in a pre-deployment stage, the cryptographic material includes at least one selected from the group consisting of an identifier of the first device in the cloud server, a first private key of an id-based cryptography system of the first device in the cloud server, a first pairwise key of the first device in the cloud server, and a counter of the first device, and if the first device is shipped to a trader, the cloud server deletes the first private key from the cloud server.. ...
