The 16th Seminar on Power Electronics for Photovoltaics and Battery Systems (June 12-13, 2023) addressed especially electrical engineers working in the PV sector. Specialists in hardware and control electronics gave an overview on all relevant topics of power electronics for PV. These include power optimizers and micro inverters, single- and three phase inverters, off-grid and battery inverters, feedback control systems, grid codes and measures for fire protection.
The seminar was held in English.
