Abstract :

By increasing use of new energy to reduce the negative effects of burning fossil fuels to supply electricity, the need for power electronic converters have become very important. Due to sudden changes in load or input voltage level, the converter used as a voltage regulator in a certain range of output voltage changes should quickly return to its reference value, which should analyze the dynamic behavior of these converters and the speed of its dynamic response to any interference is discussed. Because the initial boost converter has a delay in its transfer function due to the right half plane zero, it is possible to use structures to eliminate this delay. The use of coupled inductor in non-insulated structures is one of the structures that can be repaired in this field, which in addition to removing right half plan zero of the transfer function, increases voltage gain, reduces voltage stress on circuit semiconductors. In this paper, a new coupled inductor structure is proposed to remove the right half plan zero. The new structure will be accompanied by an increase in gain, but the voltage stress on the switch is limited, and on the other hand, due to the position of the coupled inductor, the input current for this structure will be minimized.
