In this paper, long-distance power transmission with ZVS-Ultra lift Luo converter from photovoltaic modules and transmission using an underground cable is studied. However, today's long-distance AC distribution system tends to have losses and causes voltage instability. To avoid such problems, the DC distribution system can be used and to implement DC distribution, underground cables can be used which are more reliable than overhead lines. In this paper voltage lift scheme has been used in the design of power DC-DC converters successfully which have high voltage transfer gain. The ultra-lift Luo converter with Zero Voltage Switching(ZVS) is introduced as a unique approach to the new technology, which produces high output voltage along with less switching losses. Power generation from PV modules, design and analysis of ultra lift Luo converter along with ZVS and comparison between hard switching and soft switching for long-distance power transmission is done using MATLAB/Simulink.
