Abstract
Official abstract text for this publication.
An example apparatus may include a power supply circuit comprising a first stage, the first stage comprising a current-fed topology and a transformer for isolating a primary side of the first stage from a secondary side of the first stage; a control module configured to provide control signals to one or more switches of the power supply circuit and to perform startup operations comprising: determining a peak line voltage value of an AC input voltage to the power supply circuit; initiating, when the power supply circuit is started, a hard-switching method; determining a center tap voltage of the transformer; stopping the hard-switching method, when the center tap voltage crosses a fraction of the peak line voltage value; and initiating, when the hard-switching method stops, a zero-voltage switching method with peak current mode control.
First claim
Opening claim text (preview).
What is claimed is: 1 . An apparatus comprising: a power supply circuit comprising a first stage, the first stage comprising a current-fed topology and a transformer for isolating a primary side of the first stage from a secondary side of the first stage; a clamp circuit coupled to a center tap of the transformer, the clamp circuit comprising a first element that stores energy, and a second element that controls a flow of current between the center tap and the first element; a…
