摘要：
A high static gain dc-dc converter based on the modified SEPIC converter is presented in this scheme. The preferred topology presents low switch voltage with high efficiency for low input and high output voltage applications. The configuration of this converter with magnetic coupling and output diode voltage clamping is presented and analyzed. The magnetic coupling allows to elevate the static gain maintaining a reduced switch voltage. In order to reduce the problem of overvoltage at the output diode, inclusion of a secondary voltage multiplier is made mandatory. This voltage multiplier increases the static gain of the converter and also acts as a non-dissipative clamping circuit for the output diode. The simulation is done using MATLAB/SIMULINK and results are investigated in order to validate the performance of the converter.
