this paper presents a two high step down based DC to DC converter has been suggested to investigating with various control approaches for retaining the voltage and current. The suggested converters have developed by transfromerless and having equivalent power ratings. Two diverse switching patterns are utilized in this study for mitigating the stresses across switches in the proposed system. The very first switching pattern is consisted of pulse width modulation (PWM) and 1800 phase shift angle along with LC filter in output side. This system can be operated in closed loop due to adding the LC filter in output side. The first designed converters duty cycle will be greater range and less than 0.5. For second DC-DC converter has been designed and implemented with second switching pattern for sustaining the voltage and duty cycles with LC filter in output side. In this stage, the sums of stress voltage on their switches are quite high as compared with the first designed converter. The proposed system is designed establishing MATLAB/Simulink as well as investigated in all operating circumstances. As per the simulation outcomes, the proposed closed loop system with LC filter can be shown the high performance in all dynamic operating situations.. The proposed converters will be analyzed for all in their switching patterns. In order to validate the results from theoretical, the 1st and 2nd proposed converters for 500/26 and 800/20.5 V, respectively, and 430 W, are used in MATLAB/Simulink.
