Digitally controlled power supplies offer a myriad of programmable features to thesystem engineer such as control loop modifications, sequencing and tracking,interleaving, protection and monitoring features. Configuring such a power system isgreatly eased by the use of such tools as the design wizard recently introduced as part ofPower-One's PC-based GUI for use with the Z-One? Digital IBA solution. The wizardtakes only a few basic inputs such as voltages and currents and configures a completesystem including part selections and settings. An auto-compensation feature is providedso that one can choose the output capacitors best suited for an application, then “build”the control loop around them instead of vice versa. Input and output ripple are reduced byautomatic intelligent interleaving. After the wizard is completed, the system parameterscan be manually edited if desired. The completed system can also be simulated within theGUI to see the predicted ripple and transient behavior.
