Abstract
An electrical power converter comprising two current-fed square wave chops the outputs of which are combined and rectified to yield a variable and regulated output voltage. The phase relationship of the choppers are varied to achieve output voltage control and regulation. The chopper outputs are combined in such a way that the choppers never experience the open-circuit inductance of their output transformers. This enhances frequency agility. A novel choke feed system is provided in which the choke flyback energy is absorbed and then transferred to the input of the other chopper.
