| Oct 13, 2022 at 20:13 | comment | added | winny | Solar and flyback sounds like a strange combination. Do you need to be able to transfer equal amounts of power in either direction? | |

| Oct 13, 2022 at 19:20 | comment | added | orangeandblack5 | The application is differential power processing from solar cells in a PV-to-bus architecture. Hence the need for a bi-directional, isolated power supply - it needs to be able to process power in both directions. | |
| Oct 13, 2022 at 18:20 | comment | added | Aaron | When does one want a bi-directional power supply? What is the application? Is it for something like a battery powered device that can then charge that battery from the load side? | |
| Oct 13, 2022 at 18:05 | comment | added | Tim Williams | Transformer is fine, a 5:120V or 12:60V sort of thing will be close enough. As for control, you'll need to either drive both gates from a common controller (switch + sync. rect., roles swapped as needed), or have them somehow autodetect roles, or have the rect. disabled (use body diode passively) and a controller on one or the other side takes charge. Possibly a pair of UC3843 or similar could be used that way? Depends on voltage ranges and desired logic. | |
