Power transfer between independent power ports utilizing a single transformer
First Claim
1. A power delivery network for transferring power between multiple power ports, the power delivery network comprising:
- an energy transfer element having a first winding, a second winding, and a third winding, wherein a first power converter is to be coupled to transfer power between a first power port and the first winding, and wherein a second power converter is to be coupled to transfer power between the second winding and a second power port;
a main power port to be coupled to a dc voltage; and
a main port interface coupled between the main power port and the third winding to cyclically reverse the dc voltage and to provide a cyclically reversed voltage to the third winding at a fixed duty ratio, wherein the first power converter is to control the transfer of power between the first power port and the first winding independent of the transfer of power between the second winding and the second power port, and wherein the main power port has an effective impedance less than an effective impedance of the first power port and less than an effective impedance of the second power port.

Abstract
An example power delivery network includes an energy transfer element, a main power port, and a main port interface. The energy transfer element includes multiple windings, where a first power converter transfers power between a first power port and a first winding, and a second power converter transfers power between a second winding and a second power port. The main port interface is coupled cyclically reverse a dc voltage received at the main power port and provides a cyclically reversed voltage to a third winding of the energy transfer element at a fixed duty ratio, where the transfer of power between the first power port and the first winding is independent of the transfer of power between the second winding and the second power port. Also, the main power port has an effective impedance less than an effective impedance of the first power port and the second power port.
