DC-DC power conversion and balancing circuit
First Claim
1. A system comprising:
- DC-DC power conversion circuitry including a first switch and a second switch on either side of a first transformer with a first pair of capacitors and a second pair of capacitors cross-connected across the first transformer;
balancing circuitry including a primary side of a second transformer connected between the first pair of capacitors and the second pair of capacitors of the DC-DC power conversion circuitry; and
control circuitry configured to;
determine a direction of power transfer through the DC-DC power conversion circuitry,align a primary side and a secondary side of the DC-DC power conversion circuitry based on the determined direction of power transfer,align the balancing circuitry to perform balanced or unbalanced operations, andcontrol switching of the first switch and the second switch.

Abstract
A system includes DC-DC power conversion circuitry having a first switch and a second switch on either side of a first transformer with a first pair of capacitors and a second pair of capacitors cross-connected across the transformer. Balancing circuitry includes a primary side of a second transformer connected between the first pair of capacitors and the second pair of capacitors of the DC-DC power conversion circuitry. Control circuitry is configured to determine a direction of power transfer through the DC-DC power conversion circuitry, align a primary side and a secondary side of the DC-DC power conversion circuitry based on the determined direction of power transfer, align the balancing circuitry to perform balanced or unbalanced operations, and control switching of the first switch and the second switch.
