In This paper we are presenting a bidirectional DC-DC converter is also known as dual active bridge (DAB) dc-dc converter. We presented a Z-source with bidirectional dc-dc converter by reducing the switching count by adding the passive elements we are improving the output voltage level, Comparing with the traditional bidirectional dc-dc converter, the proposed converter has an wider regulation range...
This paper presents a photovoltaic system with maximum power point tracking facility. Maximum power point trackers are so important in photovoltaic systems to increase their efficiency. The system consists of a photovoltaic solar module connected to a DC–DC buck–boost converter and load. The adaptive neuro-fuzzy inference system (ANFIS)-based maximum power point tracking (MPPT) controller is used...
Doubly Fed Induction Generator is especially used as wind power generators. An Indirect vector control is used better dynamic performance of DFIG. But the performance of closed loop control is largely influenced by the type of speed and current controllers used. Usually, proportional-integral (PI) based current controllers are used due its simplicity. But these PI controllers suffer from tuning problem...
Doubly Fed Induction Generator is especially used as wind power generators. This paper presents a control system which is based on neuro fuzzy because conventional PI controller based system does not operate satisfactorily as the operating point change. The proposed controller allows regulation in the active and reactive power efficiency. In this it takes the inputs as slip frequency, reactive power...
Solar energy is an important alternative out of the various renewable energy sources. This paper presents a new modeling of Maximum power point tracking controller with variable irradiance and variable temperature unlike the existed MPPT controller methods where either constant irradiance or constant temperature are considered as parameters. Using this proposed MPPT controller the parameters such...
