Novel method of synchronized pulsewidth modulation (PWM) has been disseminated for control of cascaded (dual) inverters of photovoltaic installation with relatively low DC-voltages of two insulated photovoltaic panels, operating under condition of low level of solar irradiance. Control regimes are characterized by overmodulation control modes of two inverters in this case. Algorithms of synchronized...
The paper presents results of dissemination of a novel method of synchronized pulsewidth modulation (PWM) for control of dual (cascaded) neutral-point-clamped inverters for photovoltaic generation. Basic system topology includes two insulated strings of photovoltaic panels, feeding two cascaded neutral-clamped inverters, connected to grid by a three-phase transformer with the open winding configuration...
The paper presents results of investigation of dual-inverter-based power conversion system with synchronized pulsewidth modulation (PWM) for photovoltaic application. This system topology includes two isolated strings of photovoltaic panels, feeding two standard three-phase inverters, connected to grid by a three-phase transformer with the open winding configuration on primary side. Algorithms of...
