Dynamic evolution control for synchronous buck DC–DC converter: Theory, model and simulation
According to the growth of power electronics application, the use of the synchronous buck converter has increased. This converter is one of the most common converter topologies that are usually used in power electronics application . Synchronous buck converters are step-down switching-mode power converters. They are popular because of their high efficiency and compact size. They are used in place of linear voltage regulators at a relatively high output power.
Synchronous buck converters are the most widely used type of power converter in battery-powered applications. Many application of power electronics converter use the synchronous buck converter as their basic topology. For example, synchronous buck converter is usually used in high efficiency power supplies.In view of this, the need of good controllers for synchronous buck converter also increases. There is an increasing need for good controllers to obtain precise output voltage regulation under different supply and load conditions.Synchronous buck converters represent a challenging field for sophisticated control techniques application due to their intrinsic nature of nonlinear and time-variant systems . In terms of converter controller design, the use of averaging or sampling techniques, followed by linearization and small-signal analysis allows the derivation of linear time-invariant
dynamic models for any converter topology. This approach enables the designer to use a simple linear controller to keep the system stable. However, they are normally dependent on the converter’s operating point . In other words, it is only applicable for a near specified operating point, while the parameters of any transfer function or state-space matrix describing a DC–DC converter may vary depending on its output voltage, input voltage or load current.
