Solar inverter efficiency

Solar inverter efficiency
Solar inverter efficiency refers to as the demand for renewable energy, solar inverters (photovoltaic inverters) market is growing. These inverters require extremely high efficiency and reliability. These inverters used in Switch Power Supply circuits were investigated and recommended the best choice for the switch and rectifier parts. The general structure of the photovoltaic inverter shown in Figure 1, there are three different inverter available. Sunlight on the solar modules are connected in series through, each module contains a set of solar cells in series (Solar Cell) unit. Direct current (DC) voltage generated by the solar module in order of several hundred volts, the values according to the number of lighting conditions module array, and the temperature of the battery modules may be connected in series.
The primary function of this type of inverter is the input DC voltage is converted to a stable value. This function is achieved through the boost converter and the boost switch and boost diode needs. In the first configuration, after the boost stage is an isolated full-bridge converter. The role is to provide full-bridge transformer isolation. The second full-bridge converter output is used from the first full-bridge DC converter stage DC into alternating current (AC). Its output is connected to another network before being filtered through the AC power grid additional double contact relay switch
