Patent ID: 6906930

Claim:
An isolated boost converter for driving an output load, comprising: an input voltage source; a boost inductor connected in series with the input voltage source; a storage capacitor which receives energy from the input voltage source, the storage capacitor having a first terminal and a second terminal; a transformer including a primary winding and secondary winding, the primary winding having a first terminal and a second terminal; first and second switches that, when both closed, couple the first terminal and the second terminal of the storage capacitor to the first terminal and the second terminal of the primary winding of the transformer, respectively, in a series connection; a clamp diode coupling the first terminal of the storage capacitor to the first terminal of the primary winding of the transformer: an output filter coupled to the output load; a rectifier coupling the secondary winding of the transformer to the output filter; and a switch control circuit to simultaneously open and close the first and second switches.
