Abstract
An apparatus includes an isolated power converter having an input connected to an input dc power source, a first output and a second output, and a non-isolated power converter having an input connected to the second output of the isolated power converter, wherein the first output of the isolated power converter and an output of the non-isolated power converter are connected in series.
Claims13
An apparatus comprising:
- an isolated power converter having an input connected to an input dc power source, a first output and a second output, wherein the isolated power converter comprises a first secondary winding, a first resonant tank, a first secondary switch network and a first output capacitor connected in cascade, and a second secondary winding, a second resonant tank, a second secondary switch network and a second output capacitor connected in cascade;
- and
- a non-isolated power converter having an input connected to the second output of the isolated power converter, wherein the first output of the isolated power converter and an output of the non-isolated power converter are connected in series.
A system comprising:
- a primary switch network configured to be connected to a power source;
- a transformer having a first secondary winding, a second secondary winding and a primary winding, the primary winding being connected to the primary switch network;
- a first rectifier connected to the first secondary winding through a first resonant tank;
- a second rectifier connected to the second secondary winding through a second resonant tank;
- an output filter connected to the first rectifier;
- and
- a power converter connected to the second rectifier, wherein outputs of the output filter and the power converter are connected in series.
