The paper presents results of investigation of dual-inverter-bases power conversion system with synchronized pulsewith modulation (PWM) for photovoltaic application. This system topology includes two insulated 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 synchronized PWM provide in this case continuous voltage synchronization both in each inverter and in the load. Simulations show a behavior of the systems with low switching frequency, with both continuous and discontinuous versions of synchronized PWM.
Algoritmus synchronizované modulace poskytuje spojitou synchronizaci napětí jak v každém střídači, tak i na zátěži. Simulace ukazují chování systému s nízkým spínacím kmitočtem pro spojitou i nespojitou verzi synchronizované modulace.
