How many volts of DC-to-AC inverter are needed to convert 12 volts of DC into 220 volts of AC?

If you really need an electrical appliance with 100500w, then the power output capability of the DC-to-AC inverter must be greater than this value. Usually, the input voltage of the DC-to-AC inverter is 12V, 24V, 36V, 48V, and there are other models with input voltage, and the output voltage is generally 220V. Of course, there are other models that can output different required voltages. The key parameters of the DC-to-AC inverter are: output power, conversion efficiency, and output waveform quality. Just compare these parameters to know the quality of this DC to AC inverter. DC-to-AC inverter is a common equipment, as long as it is a common model, it is generally sold in electrical repair points and almost all electronic markets, and as long as it is technically acceptable, electrical repair shops can repair it. The electronic market is even more repairable. If it is a very useful model or the power is very high, you can only go to the electronic market or order it online. A DC-to-AC inverter is a device that converts DC power into AC power (generally 220V, 50Hz sine wave). It does the opposite of a rectifier, which converts AC power to DC power. The DC-to-AC inverter consists of an inverter bridge, a control unit and a filter circuit. Widely used in air conditioners, electric tools, computers, televisions, washing machines, refrigerators, massagers and other electrical appliances. The following points must be paid attention to when selecting and using the DC-to-AC inverter: 1) The DC voltage must match; each DC-to-AC inverter has a nominal voltage, such as 12V, 24V, etc., and it is required to select the battery voltage must be It is consistent with the nominal DC input voltage of the DC-to-AC inverter. Such as 12V DC to AC inverter must choose 12V battery. 2) The output power of the DC-to-AC inverter must be greater than the maximum power of the electrical appliance; especially for some equipment with large starting energy requirements, such as motors and air conditioners, additional power margins are required. 3) The positive and negative poles must be connected correctly. The DC voltage connected to the DC to AC inverter is marked with positive and negative poles. Generally, red is the positive pole (+), black is the negative pole (-), and the positive and negative poles are also marked on the battery, red is the positive pole (+), and black is the negative pole (-). ), negative to negative (black to black). The diameter of the connecting wire must be thick enough, and the length of the connecting wire should be reduced as much as possible. 4) The charging process and the inverter process cannot be carried out at the same time to avoid damage to the equipment and cause failure. 5) The shell of the DC to AC inverter should be properly grounded to avoid personal injury due to leakage. 6) In order to avoid electric shock injury, it is strictly forbidden for non-professionals to dismantle, repair and refit the DC-to-AC inverter.
