In my project, I have two PCBs, each containing a fuel injector actuation circuit powered by a HRL3024S200P converter. Both PCBs include four injector circuits, which operate continuously. However, the injectors (4) are connected to only one of the boards at any given time, based on a selection for redundancy. The issue I'm encountering is that the board actively controlling the injectors maintains the set voltage, while the other PCB experiences a voltage drop. The voltage on the inactive PCB only returns to the set value when the circuit is turned off and on again. How can I resolve this issue?
I have included the circuit diagram for reference.
