The function and adaptation scene of inverter
The inverter is a device that converts DC power (battery, battery) into alternating current (typically 220V, 50Hz sine wave). It consists of an inverter bridge, control logic and filter circuits. Widely used in air conditioners, home theaters, electric grinding wheels, power tools, sewing machines, DVD, VCD, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. In foreign countries, because of the high penetration rate of automobiles, you can use the inverter to connect the battery to drive the electrical appliances and various tools.
Simply put, an inverter is an electronic device that converts low voltage (12 or 24 volts or 48 volts) direct current to 220 volts AC. Because we usually use 220 volt AC to be converted to DC, and the inverter has the opposite effect, hence the name. We are in a “mobile” era, mobile office, mobile communication, mobile leisure and entertainment. In the mobile state, people not only need low-voltage DC power supplied by batteries or batteries, but also need 220 VAC which is indispensable in our daily environment. The inverter can meet our needs.
The inverter itself consumes a portion of its power when it is operating, so its input power is greater than its output power. The efficiency of the inverter is the ratio of the output power of the inverter to the input power, that is, the efficiency of the inverter is the output power than the input power. If an inverter inputs 100 watts of direct current and outputs 90 watts of alternating current, then its efficiency is 90%.
Inverter use range:
1. Use office equipment (such as: computers, fax machines, printers, scanners, etc.);
2. Use life appliances (such as: game consoles, DVDs, stereos, cameras, electric fans, lighting, etc.);
3. Or when you need to charge the battery (cell phone, electric shaver, digital camera, camera, etc.);
