This example implements the control for a three-phase PV inverter. Such a system can be typically found in small industrial photovoltaic facilities, which are directly…
Some power sources, like solar panels, present power characteristics that strongly depend on the operating conditions. In such cases, Maximum Power Point Tracking (MPPT) is often applied to maximize the extracted power.
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.
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 example generates three phase alternating currents from a voltage source inverter in an open loop manner. It can be used in a grid-forming application.
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)
Second-order Generalized Integrators (SOGI) have recently been proposed for use as phase detectors for PLL implementations. These structures are essentially notch filters (band-pass) that can be easily tuned to the grid frequency.
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.
