چکیده :

This paper proposes a family of non-isolated highgain DC-DC converters that have these merits: (i) both the input and output currents are continuous, and the input/output filter capacitors experience less current stress; (ii) the load-source common ground has been provided; (iii) only one switch has been employed in the proposed topologies which increases its reliability; (iv) the employed switch in the topologies is lowsided which leads to its easy drive circuit; (v) higher voltage gains are accessible with lower duty cycle percentages; (vi) the semiconductors experience low voltage/current stresses that lead to high efficiency. The proposed topologies are discussed in both ideal/non-ideal modes. Finally, the simulation results from PLECS are presented.
