Why Do We Need Household Inverter?

All in all, the role of a household inverter is an electronic device that converts low-voltage (12 or 24 volts or 48 volts) direct current into 220 volt alternating current. Unlike the case where we usually rectify 220 volt AC power into DC power for use, the inverter has the opposite effect, hence the name. We are in a "mobile" era, mobile office, mobile communication, mobile leisure and entertainment. In a mobile state, people not only need low-voltage DC power supplied by batteries or batteries, but also need 220 volt AC power that is indispensable in our daily environment. The appearance of inverters can meet our needs.

What is the significance of the appearance of household inverters?

1. With a household inverter, DC power (battery, switching power supply, fuel cell, etc.) can be converted into AC power to provide stable and reliable power protection for electrical appliances, such as handheld PCs, mobile phones, laptops, digital cameras, and all kinds of Instruments etc.

2. household inverters can also be used in conjunction with generators, which can effectively save fuel and reduce noise.

3. In the fields of wind energy and solar energy, household inverters are even more indispensable.

4. Small household inverters can also use automobiles, ships, and portable power supplies to provide AC power in the wild.

What are the uses of household inverters in real life?

Office using equipment: fax machines, printers and monitors, laptops, mobile phones.

Household appliances: TVs, video recorders, game consoles, stereos, VCDs, DVDs, refrigerators, etc.

Outskirts tourism: outdoor lighting, microwave ovens, cooking, etc.

Outdoor work: power tools, vehicle assistance, rescue and disaster relief, commercial promotion, etc.

Leisure and entertainment: mobile phones, PDAs, digital cameras, digital video cameras, battery charging, GPS satellite navigation, etc.

What is the working principle of household inverter?

household inverter is a DC transformer, which is actually an inverter process. The frequency converter converts the AC voltage of the power grid into a stable 12V DC output, and the household frequency converter converts the 12V DC voltage provided by the adapter into high-frequency and high-voltage AC; Both sides also adopted the more widely used pulse width modulation (PWM) technology. The core part is PWM embedded controller, the adapter adopts UC3842, and the household inverter adopts tl5001 chip. The working voltage range of tl5001 is 3.6 ~ 40V. There are error amplifier, regulator, oscillator, PWM generator with dead band control, low voltage protection circuit and short circuit protection circuit.

Input interface part: the input part has three signals, input VIN 12V DC, working activation voltage ENB and instrument panel current control signal dim. Vin is provided by the adapter and ENB voltage is provided by MCU on the main board. Its value is 0 or 3V. When ENB = 0, the domestic inverter does not work; when ENB = 3V, the domestic inverter works normally; The dim voltage range provided by the main board is 0 ~ 5V. Different dim values are returned to the loop terminal of the PWM controller. The current supplied to the load by the household inverter will also be different. The smaller the dim value, the smaller the output current of the household inverter.
