solar panel manufacturers - — Guangdong energy technology co. , LTD. , solar panels, photovoltaic (pv) grid inverter working principle of solar panel array issued a direct current (dc) in the sun, solar panels before being incorporated into the power grid must be converted into alternating current (ac). Therefore, no matter what technology, inverter, the basic design idea is very clear. Its core is to convert dc voltage to the grid voltage, namely in the process of transformation, the positive and negative connection of dc conversion, thus forming the direction change of alternating current. Therefore, the inverter bridge are key components of the switch. Switch on one side of the bridge connected to the input DC power supply, on the other side is connected to the ac grid. In the process of operation, only two relatively closed switch at the same time. If the switch of the bridge is set to the same as the grid frequency switching speed, the output side of the theory, the bridge can be connected to the grid. However, because this did not change the square wave output current is strength, so it is necessary on the output side installation with iron core inductors, to control the output current for sine wave shape. Bridge connect and disconnect pulse process is required to form smaller associated with pulse current component, is used to control the current of inductor. Frequency of pulse is 20 KHZ, thus can fully formed alternating current (ac) of 50 KHZ.
