3.5.8 Power Stack Adapter
The Power Stack Adapter (PSA) acts as the physical interface between the power unit and
the open-loop/closed-loop controller. This is where the galvanic isolation (electrical coupling
via light) between the power unit and the open-loop controller takes place. Data is exchanged
between the Power Stack Adapter and the Control Unit via the DRIVE-CLiQ high-speed serial
communication interface.
