摘要： A method of operating a flyback converter is provided. The flyback converter comprises a transformer having a primary side winding and a secondary side winding, a primary switch at the primary side of the transformer and a secondary switch at the secondary side of the transformer, and a control unit. At the end of a switching cycle, before turning on the primary side switch: the control unit generates a Zero Voltage Switching (ZVS) pulse in the secondary side winding, such that the parasitic capacitor of the primary side switch is discharged. Consequently, the primary side switch is turned on in ZVS or near ZVS conditions.

摘要： There is provided a method, the method including the steps of: at a key generator subsystem: generating a public-private encryption key pair for a device, and transmitting the generated public key to be registered on a blockchain; at one or more processors: encrypting a digital asset via the public key of the device, and linking or associating the encrypted digital asset to a non-fungible token (NFT), in which the NFT is associated with a smart contract written on the blockchain; and at the device: requesting access to the NFT-linked digital asset; receiving the NFT-linked digital asset when the requirements of the smart contract are met; and decrypting the NFT-linked digital asset using the private key.
