In this paper the dual implementation of the MPPT technique TEODI is presented and discussed. Such a new technique will be called D-TEODI. As well as TEODI, also D-TEODI is suitable for DMPPT PV applications. Its main advantages, as for TEODI, are the simplicity of implementation, the absence of memory and multiplication operations, and the high MPPT efficiency obtainable when the PV modules belonging...
This paper presents a simple, robust, and fast synchronization method to detect the phase angle of the positive sequence of a three-phase ac system. The algorithm was derived from a standard phase-locked-loop (PLL) circuit based on the pq theory, but a feedforward action is implemented to guarantee high dynamic performance in conjunction with a modified feedback action to reduce the phase-angle estimation...
In this paper, a control strategy for a bidirectional DC/DC power converter is discussed, and the logics to guarantee the operation correctness in various operative modes and for safety requirements are considered. In Buck (or step- down) mode, a voltage PI regulator is proposed, whereas in Boost (or step-up) mode an inner current control loop is introduced to guarantee a more effective current tracking,...
