The paper reviews two tools to address system level control issues in power electronic distribution systems: the positive feedforward control technique and the digital network analyzer method. Using the positive feedforward control technique, a DC-DC converter can at the same time control its output voltage and stabilize the input DC bus. The digital network analyzer method gives a converter the capability to measure small-signal transfer functions and impedances at its terminals. This information can be used for monitoring and control adaptation. Examples of applications of the two methods are described.
