Minimization of Switching Losses in Grid Interfaced PV Inverters using SHE Modulation Strategy

minimization of the switching losses in high power induction furnaces using an analog state feedback controller

due to the high efficiency and low switching losses of resonant power convertors in comparison with switching convertors, nowadays there is a growing trend towards these convertors. however, because of the high frequency of switching in such convertors, it is quite difficult to present an efficient control method. in this paper, based on the state feedback method and using pole placement techni...

Multilevel Inverter by using Switching Capacitor in PV Grid

In this paper, we are using multilevel inverter by using switching capacitor for PV grid. Now a day’s multilevel inverters have become more popular over the years in electric high power application with the promise of less disturbances and the possibility to function at lower switching frequencies than ordinary two-level inverters. So by cascading multilevel inverter the output voltage will be ...

Review on Single-phase PV Inverters for Grid-connected Applications

In this paper, a review of PV inverters is reported based on converter characteristics as the number of energy processing stages, the presence of a transformer (high-frequency or 50Hz transformer), and the adopted configuration of the PV field. In particular, the considered solutions have been evaluated depending on efficiency, input current ripple and life-time of the capacitors coupling with ...

Flexible Power Regulation of Grid-Connected Inverters for PV Systems Using Model Predictive Direct Power Control

This paper presents a Model Predictive Direct Power Control (MPDPC) strategy for a gridconnected inverter used in a photovoltaic system, as found in many distributed generating installations. The controller uses a system model to predict the system behavior at each sampling instant. Using a cost function, the voltage vector with least power ripple is generated. The resultant voltage vector is a...
