A high static gain DC-DC-quadrupler converter with coupled-inductors

Since the classical DC-DC boost and buck-boost converters are unable to present high static-gain values due to its design configurations, this papers proposes a high static converter, which integrates the coupled-inductor technique, giving a level of freedom in the control of the static gain, and the voltage multiplier technique, which present low values for losses in the components of the circuit, thus elevating the overall efficiency of the converter. The operation principles, the theoretical analysis, the stages of operation and the experimental results are presented for this converter. To validate and to verify the performance of the proposed converter, a Vin=24V, Vout=432V and P=400W prototype is implemented in the laboratory.
