Dual inverters with synchronized PWM for photovoltaic generation
Analysis of operation of photovoltaic system on the base of dual inverters with synchronized pulsewidth modulation (PWM), supplied by two strings of photovoltaic panels and connected to a grid by a three-phase transformer with the open winding configuration on primary side, has been performed.

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Analysis of operation of photovoltaic system on the base of dual inverters with synchronized pulsewidth modulation (PWM), supplied by two strings of photovoltaic panels and connected to a grid by a three-phase transformer with the open winding configuration on primary side, has been performed. Algorithms of synchronized PWM are based in this case on continuous control of the switching frequencies of two inverters as function of magnitude of the DC-links voltage, providing both continuous voltage synchronization in each inverter and in the load, and also an improvement of operation of photovoltaic systems during solar irradiance fluctuation. |
