Beschreibung
Zusammenfassung:	The utility model discloses a non - isolation full -bridge grid -connected PV power generation system, adopt the non - isolation full bridge inverter in sixmo pass, when power transfer mode, it flows through 3 switching elements to be incorporated into the power networks half power frequency cycle of electric current, and 2 switching elements are flow through to half power frequency cycle in addition, the on -state loss has been reduced, it is balanced to be favorable to the thermal stress, and still satisfy the requirement that afterflow stage photovoltaic array direct current side and electric wire netting break away from, the restriction of non - isolation grid -connected PV power generation system to the common mode leakage current has been satisfied betterly.
