Abstract:
      To improve the DC-DC gain, a new type of high-gain Boost converter was proposed based on switched inductor/capacitance. The new converter combined the advantages of switched inductor/capacitance and reduced the voltage stress of power devices, thus realizing the selection of power devices with lower conduction resistance. Moreover, the conduction loss of power devices was reduced, so that the converter could be applied to occasions with higher-gain and smaller voltage stress of devices. The theoretical analysis and simulation of the working principle of the new type high-gain Boost converter were conducted, and a prototype was designed and manufactured. Experiments verified the theoretical analysis.
