A Coupled Inductor-Based Dual-Switch High Step-Up DC-DC Converter with Common Ground
Abstract
A non-isolated dual-switch high step-up DC-DC converter with a two-winding coupled inductor (CI) is proposed in this paper. The proposed topology is achieved by using a combination of the diode-capacitor voltage multiplier cells and a CI, resulting in the high voltage gain and low voltage stress on the power switches. The low voltage stress across power switches helps to reduce the power loss of the converter by employing low-voltage-rating power switches. The proposed topology has a continuous input current, and the common electrical ground between the input and output ports is preserved. The steady-state analysis is done for the proposed converter, and superiorities of the proposed converter over the existing topologies are demonstrated using a comparison study. To verify the steady-state analysis, simulation results of a 40 V to 400 V, 400 W converter are reported; the simulation is done in PLECS software.
