This work presents a modular architecture based on the input series output parallel (ISOP) connection of Full Bridge Phase Shifted power converters with a common input filter. The modeling of the converter architecture taking into account the effect of the common input filter is the previous step to the controller design in order to ensure a proper regulation of external converter quantities, such...
The design of linear compensators is usually based on the frequency response of the system, considering phase margin PM and cross-over frequency fc as the initial specifications. Applying the k-factor method for synthesis of linear compensators, not all combinations of fc and PM yield feasible or stable designs, and in many cases the design procedure is based on a trial and error procedure. The objective...
This paper is focused on the assessment of a modular architecture based on the Dual Active Bridge (DAB) converter in input series, output parallel (ISOP) connection. Previous works have dealt with modeling and control techniques to ensure a proper voltage and power sharing among the modules. In this paper an experimental evaluation of the behavior of the DAB in ISOP connection is carried out in order...
This paper presents the optimized control of a three-phase grid connected inverter, considering as basis of analysis the observation of the dynamics of the system with two inputs and two outputs (TITO SYSTEM). This model allows the design of the inverter control in a direct way, by means of two PI controllers to control the instantaneous active and reactive power. By means of the control of the instantaneous...
In this work a very simple structure for the implementation of a digital reconfigurable compensator based on specific hardware is presented. Its main advantages are the easy way to change the transfer function by changing the clock frequency of the compensator and the reduction of the required digital resources. This approach can be used in systems implementing capabilities such as autotuning, adaptation...
