Inverter is a power converter that can convert direct current energy (such as batteries, storage bottles) into alternating current (generally 220V,50Hz sine wave), which is composed of inverter bridge, control logic and filter circuit. Inverter is widely used in air conditioning, home theater, electric grinding wheel, power tools, sewing machine, DVD, VCD, computer, TV, washing machine, range hood, refrigerator, video recorder, massager, fan, lighting and so on.
Inverter principle:
The inverter converts direct current into alternating current, and its basic principle is that by converting direct current into alternating current, the frequency and voltage of alternating current are equal to the frequency and voltage of the original direct current, so as to achieve the conversion of current.
The photovoltaic inverter is mainly composed of input filter circuit, DC/DCMPPT circuit, DC/AC inverter circuit, output filter circuit and core control single circuit. A typical solar inverter includes a DC-DC stage connected to the solar panel that enhances the inverter input voltage to enable it to feed power into the grid, which often has a maximum power point tracking (MPPT knife function) and a full bridge connected to the grid for DC-AC.
Inverter is an important power converter, which can convert direct current into alternating current, and is widely used in various electronic devices and household appliances of solar panels.
