What is an inverter?

The inverter is a device that converts DC power (battery, storage battery) into AC power (generally 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVD, VCD, computers, TVs, washing machines, range hoods, refrigerators, VCRs, massagers, fans, lighting, etc. In foreign countries, due to the high penetration rate of automobiles, the inverter can be used to connect the battery to drive electrical appliances and various tools to work when going out to work or travel. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. Some higher power inverters need to be connected to the battery through connecting wires. Connect household appliances to the output of the power converter to use various appliances in the car. The electrical appliances that can be used are: mobile phones, notebook computers, digital cameras, cameras, lights, electric shavers, CD players, game consoles, handheld computers, electric tools, car refrigerators and various travel, camping, medical emergency appliances Wait.

The inverter is a DC to AC transformer, which is actually a process of voltage inversion with the converter. The inverter converter converts the AC voltage of the grid into a stable 12V DC output, while the inverter converts the 12V DC voltage output by the Adapter into a high-frequency high-voltage AC; both parts also use more pulse width modulation (PWM) technology. Its core part is a PWM integrated controller, the Adapter uses UC3842, and the inverter uses TL5001 chip. The working voltage range of TL5001 is 3.6 ~ 40V. It has an error amplifier, a regulator, an oscillator, a PWM generator with dead zone control, a low voltage protection circuit and a short circuit protection circuit inside. .

The inverter converts DC power (battery, storage battery) into AC power (generally 220v50HZ sine or square wave). In layman's terms, an inverter is a device that converts direct current (DC) into alternating current (AC). It consists of inverter bridge, control logic and filter circuit. ?[1]?? Widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVD, VCD, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. Simply put, an inverter is an electronic device that converts low voltage (12 or 24 volts or 48 volts) direct current into 220 volts alternating current. Because we usually use the 220-volt alternating current rectifier to turn it into direct current, and the inverter acts in the opposite direction, hence the name. We are in a "mobile" era, mobile office, mobile communication, mobile leisure and entertainment. In the moving state, people not only need low-voltage DC power supplied by batteries or storage batteries, but also need 220-volt AC power, which is indispensable in our daily environment, and inverters can meet our needs.

The inverter itself also consumes part of the electricity when it is working, 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 ratio of the output power to the input power. For example, if an inverter inputs 100 watts of direct current and outputs 90 watts of alternating current, then its efficiency is 90%.
