This paper presents a study of a new topology of a DC–DC converter titled double quadratic boost non-isolated. This converter has high static gain and proposes to reduce the voltage stress on the switches, where the maximum voltage value at each switch is equal to half of the total output voltage. The paper first presents the theoretical analysis of the converter operating in open loop. The objective of the work is the mathematical modeling and control strategy of the converter, as well as validation through closed loop experimental results. In addition, we present the results of practical tests to demonstrate the operation of the converter, such as the experimental static gain curve, the practical efficiency of the converter, and the output voltage control, as well as the capacitor voltage swing control. The authors designed the prototype for 1 kW, with a switching frequency of fs=50 kHz, with FPGA-based control and modulation.
