  • photovoltaic inverter structures - PV inverter, key element of grid-connected PV power systems;
  • converting DC power generated by PV panels - into grid-synchronized AC power;
  • first grid-connected PV plants - of 1980s, as thyristor-based central inverters;
  • IGBT and MOSFET technology - for PV inverters, except module-integrated ones;
  • relevant actual transformerless PV inverter structures - derivatives of main families;
  • inverter structures - from h-bridge topology;
  • h-bridge or full-bridge (FB) converter family - by W. Mcmurray, 1965, reference in power electronic converter technology development;
  • H5 inverter topology (SMA);
  • ‘modified’ FB topology - full-bridge zero voltage rectifier;
  • inverter structures, from NPC topology - versatile, used in single-phase and three-phase inverters
