“…Park transformation is used to convert the two-phase stationary frame (α-β*) (1) into the two-phase rotating frame (d-q) which is synchronous with the grid voltage phase θ (2). The two-phase voltages in reference to the dq reference frame are converted in stationary quantities α-β using the inverse matrix of the reference frame transformation [26]:…”

In this paper, a procedure to simulate an electronic power converter for control design and optimization purposes is proposed. For the addressed application, the converter uses SiC-MOSFET technology in bidirectional battery chargers composed of two power stages. The first stage consists of a single-phase AC/DC power factor correction synchronous rectifier. The following stage is a DC/DC dual active bridge. The converter has been modulated using a phase-shift technique which is able to manage bidirectional power flows. The development of a model-based simulation approach is essential to simplify the different design phases. Moreover, it is also important for the final validation of the control algorithm. A suitable tool consisting of a system-level simulation environment has been adopted. The tool is based on a block diagram design method accomplished using the Simulink toolbox in MATLAB™.

“…Two of these, applied to an αβ-PLL, will be described here: one is based on the previously described decoupling networks, while the other is based on multi synchronous reference frame filtering, a technique that has already been applied successfully in active filter current control, [27]- [29]. The proposed scheme stems from the work of the authors carried out on single phase PLLs, [30], and on speed and position estimation for ac drives with low-resolution position sensors, [31]. The dynamic performances of the resulting fault-decoupled PLLs will be analyzed for specific grid faults, with superimposed harmonic distortion.…”

Frequency and phase angle estimation is a key aspect\ud for grid-connected inverters that are required to guarantee lowvoltage\ud fault-ride-through capability. Over the past two decades,\ud a number of estimation algorithms have been proposed, mostly\ud based on the well-known phase-locked loop (PLL). It has been\ud demonstrated that standard PLLs do not perform correctly in\ud abnormal grid conditions, due to the oscillations produced in the\ud frequency and phase angle estimates by the voltage harmonics. This\ud paper introduces a new, general approach to harmonic decoupling\ud and presents a highly intuitive and simple scheme, applying it to\ud an αβ-PLL; compensation of any desired number of harmonic\ud components is possible. Two implementations of this decoupling\ud scheme are presented. It is shown that the performances of the\ud resulting fault-decoupled PLLs are comparable with those of other\ud advanced frequency and phase angle estimation structures
