Claim of US Patent No. 10,284,083

8. An inverter, comprising:a DC/AC converter, and
a DC/DC converter, comprising:
a first low-voltage terminal point, a second low-voltage terminal point and a third low-voltage terminal point, and
a first high-voltage terminal point and a second high-voltage terminal point,
wherein the first low-voltage terminal point and the first high-voltage terminal point are directly connected to one another,
wherein an actively drivable switching element, a capacitor and a further switching element are connected in series between the first high-voltage terminal point and the second high-voltage terminal point, and
wherein the capacitor is connected between the second low-voltage terminal point and the third low-voltage terminal point,
a further capacitance directly connected between the second low-voltage terminal point and the third low-voltage terminal point,
wherein the further capacitance is decoupled from the capacitor at two terminals by two inductors, respectively
wherein the DC/AC converter is connected to the first and second high-voltage terminal points of the DC/DC converter and feeds into an AC voltage grid.
