Abstract
A DC AC inverter system includes a full bridge DC AC inverter, a first module with a first capacitance connected to a positive DC input and an intermediate output, and a second module with a second capacitance connected to a negative DC input and to the intermediate output, wherein the first and second capacitance is greater than PΔA/(VΔ*Vnom*2πf); (a) PΔ is a predetermined power imbalance between a first output and the intermediate output and a second output and the intermediate output; (b) Vnom is a predetermined nominal output voltage between the first output and the intermediate output (V1) and the second output and the intermediate output (V2); (c) VΔ is a predetermined fraction of voltage difference, relative to Vnom, between V1 and V2 when there is a power imbalance PΔ; and (d) f is a frequency of V1 or V2.
