Abstract

To interface low-voltage dc-output power sources to ac grid, the split dc-bus dc-ac inverters driven by step-up isolated dual-output DC-DC converters can be a solution. When the split dc-bus dc-ac inverter is loaded with single-phase ac or unbalanced three-phase ac, current ripples will propagate through the DC-DC converters at frequencies that are related to the ac side fundamental. For the DC-DC converter close-loop voltage regulation to be robust against the disturbance introduced by those low frequency current ripples, a novel control architecture is proposed. In this paper, a combined control structure for dual-output DC-DC converters with common mode (CM) and differential mode (DM) compensation loops are presented. Simulation and experimental results have been provided for validation.
