The problem of energy supply has long been one of the most important human problems in the last two centuries, but due to its destructive effects on the environment and, more importantly, the depletion of these resources, researchers are looking to replace it with renewable energy. The most accessible renewable energy is solar energy. The main problem with solar energy is its low initial cost, high commissioning, and low efficiency. Photovoltaic systems are one of the most important applications of solar energy, and the main focus of this dissertation is on the inverter of these systems. So far, the structures of many photovoltaic systems have been described in various articles, the most recent of which is the AC module, which is widely used for home and auto applications. The AC module is a combination of a solar cell unit and a network-connected inverter. One of the most important parts of an AC module is its inverter, which has many problems and issues in its optimal design. The most important design concerns of these systems include high efficiency, long service life, elimination of ground leakage current, finding the maximum power point, reducing the volume, weight and price of the system, reliability and protection against all kinds of errors. This dissertation first describes the types of inverters in the photovoltaic system and identifies issues and concerns in photovoltaic systems, the main of which is to reduce the efficiency of these systems, so a brief introduction to the various methods of increasing interest rates Expressed for the structure of the AC module. This proposed structure is one of the stated inverters, simulated and studied by one of the methods of increasing interest. This proposed structure has many features and advantages over similar structures expressed in other studies. High efficiency and simple control are two of the most important features of this proposed structure.
