A review on non-isolated low-power DC–DC converter topologies with high output gain for solar photovoltaic system applications

Abstract The major challenges of the high-gain DC–DC boost converters are high-voltage stress on switch, extreme duty ratio operation, diode reverse-recovery and converter efficiency problems. There many topologies that have been widely developed to overcome those problems, especially for solar photovoltaic (PV) power-system applications. In this paper, 20 low-power selected from available literature. Then, seven prospective with conversion ratios >15 thoroughly reviewed compared. are: (i) voltage-multiplier cell, (ii) voltage doubler, (iii) coupled inductor, (iv) a inductor switch capacitor, (v) switched (vi) cascading techniques (vii) voltage-lift techniques. Each topology has its advantages disadvantages. A comparison is provided in terms number components, hardware complexity, maximum switch. These presented detail. So, future, it will be easier researchers policymakers choose right build them into PV systems based their needs.
