Modular inverters have a closed circuit when each inverter shares the common DC source and AC bus. The cir-culating current is generated by diferences in each inverter, such as hardware parameters and control process. The circulating current deteriorates the output current quality and degrades the reliability of the parallel system [12–15].
One of the most important advanced and efficient technologies in converting DC electrical energy to AC is switched-capacitor multilevel inverters with reduced charging current, which enable output voltage boosting. This paper proposes a structure based on the switched-capacitor technique.
These modular inverters ofer convenient maintenance and an adjustable power rating. However, when the inverters share a common DC source and AC bus, a circulating current is generated, which causes output current distortion and system power losses.
The third part defines the cell which generated the SMPS. For example, the second buck converter of cell E will be referred to as b2E. Differential-mode (DM) dc/ac inverters have been proposed in the literature mainly in the context of low-power renewable energy systems.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
The low-frequency cir-culating current is parameter related, such as imperfect sym-metry in hardware and dependent control of parallel inverter dead time [18, 19]. By …
