The need for high power apparatus in industry has increased in recent years. Multilevel inverters have developed as easy alternatives for such power requirements. Multilevel inverters consist of a group of semiconductor switches and a set of voltage source components like capacitors or independent sources. The basic concept of these inverters depends on using this series of switches and sources...

This paper presents a study on Proportional Resonant (PR) current control with additional PR harmonic compensators for Grid Connected Photovoltaic (PV) Inverters. Both simulation and experimental results will be presented. Testing was carried out on a 3kW Grid-Connected PV Inverter which was designed and constructed for this research. Keywords—Inverters, Proportional-Resonant Controllers, Harmo...

The parallel interleaved three-phase inverters are suitable for high-power applications due to the current ripple canceling effect. power density and efficiency can be further improved with prediction (CRP) based high frequency zero-voltage switching (ZVS). However, variable increases rapidly as decrease, resulting in higher turn-off loss at light load despite elimination of turn-on loss. In th...
