A biasing circuit for a flyback converter can include a rectifier electrically coupled to an inductor of the flyback converter for generating a direct current signal from an alternating current signal outputted by the inductor in response to the inductor transferring an amount of energy to another inductor. The biasing circuit can also include a storage device electronically coupled to the rectifier to receive the direct current signal and store a charge. The biasing circuit can further include a limiting device electronically coupled to the storage device to provide an amount of the charge that is stored in the storage device to an input lead of a switch of the flyback converter for biasing the switch.
