This note introduces the general operating principles of a simple Proportional-Integral PI controller. An example of current control for a boost converter is provided, along with a practical control implementation.
Vector current control is a widespread current control technique for three-phase AC currents, which uses a rotating reference frame, synchronized with the grid voltage (dq-frame)
This note introduces the general operating principles of cascaded control and then details a possible design methodology. Then, an example of cascaded voltage control for a boost converter is provided.
This note presents several modulation techniques to operate a Dual Active Bridge (DAB) converter. First, the topology and the theoretical aspects of the Dual Active…
In voltage source converters, pre-charging the inverter DC bus is required before connecting it to external voltage sources, so that to avoid inrush currents that may be destructive.
This page presents a dead time selection method that can be used with imperix power modules. Appropriate dead time selection is crucial to guarantee the…
