چکیده
In this paper, a novel control strategy for a nonlinear boost inverter is proposed. The idea is based on generating an autonomous oscillator that does not need an external reference signal. This aim is achieved by using energyshaping methodology with a suitable Hamiltonian function which defines the desired system behavior. A phase controller is added to the control law in order to achieve 180◦-synchronization between both parts of the circuit as well as synchronize the voltage output with a pre-specified signal, e.g. synchroThis research was funded by the MICINN-FEDER grant DPI2009-09961. ∗ Email addresses: [email protected] (Carolina Albea ), [email protected] (Francisco Gordillo,), [email protected] (Carlos Canudas-de-Wit,) Escuela Superior de Ingenieros, Avd de los Descubrimientos s/n, 41092, Sevilla, Spain, Tlf: +34 954 48 74 87, Fax:+34 954 48 73 40 Escuela Superior de Ingenieros, Avd de los Descubrimientos s/n, 41092, Sevilla, Spain, Tlf: +34 954 48 73 45, Fax:+34 954 48 73 40 GIPSA-Lab, BP. 46, 38402, ST Martin d’Hères, France, Tlf: +33 476.82.63.80, Fax:+33 476.82.63.88 Preprint submitted to Elsevier April 20, 2010 nization with the electrical grid. An adaptive control is designed for dealing with the common problem of unknown load. In order to analyze the stability of the full system, singular perturbation approach is used. The resulting control is tested by means of simulations.

In this paper, a simple three-phase grid-connected photovoltaic (PV) inverter topology consisting of a boost section, a low-voltage three-phase inverter with an inductive filter, and a step-up transformer interfacing the grid is considered. Ideally, this topology will not inject any lower order harmonics into the grid due to high-frequency pulse width modulation operation. However, the non-idea...
