In this last case, the EL is behaving like a three-phase rectifier.
PID control
The EUT side control algorithm is based on a traditional current PID controller. In case controlling
power, or even the impedance, both magnitudes are decoupled and translated to current set
points on each control loop.
The following diagram illustrates how the algorithms operate:
Both in voltage mode and current mode, the equipment is regulated for the limits imposed by
the interface: maxIout, minIout, maxVout and minVout. In case that those limits are not
configured, the equipment is protected by the natural limits (110% of the nominal current).
The following table explains how those limits work.
