This paper suggests using a hybrid converter to move power from the solar power source to the load. Due to its dependence on solar power intensity, solar power generation does not maintain a constant power level. As a consequence of this, the proposed system necessitates the use of a battery in order to achieve a power balance between solar power and load. When the proposed circuit uses the battery to balance power, it needs a charger and a discharger. The proposed converter can be made simpler by combining the functions of charging and discharging the battery with those of a buck-boost converter and a flyback converter. Zero-voltage switching (ZVS) can be used to reduce the switch's switching loss when the proposed converter is in the discharging mode at the turn-on transition. Additionally, the hybrid converter that is currently under consideration has a number of advantages, some of which include a lower component count, a lighter weight, a smaller size, a higher conversion efficiency, and so on. The proposed model can achieve an efficiency of 85% under full load conditions and outperforms its hard-switching counterparts in terms of conversion efficiency when used in the discharging mode by 4%. Experiments have been conducted on a prototype with a maximum output power of 20 W and an output voltage of 10 V to determine its viability. It is suitable for a nighttime electronic sign with a 200 W or less LED [1].
