With more and more applications of inverter power supplies, the demand for the development of inverter power supply technology is also increasing. At present, the design of inverter power supply adopts a structure composed of discrete components designed by pure hardware. As the number and type of appliances used by people increase, the higher the waveform and capacity requirements of the inverter power supply, the higher the complexity of the inverter power supply design and the more components used. However, due to the excessive number of components and the poor stability of the power supply, the entire system is often damaged due to poor quality of a component. In addition, the traditional inverter power supply is based on the design of analog components and has no programmability, which makes the reversible power supply less scalable and has no display function. Therefore, the microcontroller is very important as the master chip of the inverter power supply. With the deve...

The time of the battery against the load by the inverter: Working time = battery capacity × battery voltage × 0.8 × 0.9 / load power For example, a 12V 60A battery for a 220V 100W bulb: Working hours = 12 (V) × 60 (AH) × 0.8 × 0.9 / 100 (W) = 5.18 (hours)   12V - battery voltage; 60 (AH) - battery capacity; 0.8 - battery discharge coefficient (constant); 0.9 - inverter conversion efficiency; 100 (W) - bulb nominal power; 5.18 (hours) - Calculated time for a 100W light bulb to work when powered by a 60AH battery. (Specifically how much time to look at your battery performance is good or bad) Ice cream machine is an inductive load electrical equipment, its own start-up current, instant power, such as the refrigerator compressor, motor drills and other practical power is generally one-fourth to one-third of the rated power . It is recommended that you use a pure sine wave inverter with a minimum of 3000W .

I have buy a 2000W inverter. Does it can load kettle to boil water? 1. There is no problem with boiling water. The inverter is plugged into the cigarette lighter or directly connected to the battery, and then converts the 12V or 24V battery voltage to 110V or 220V ac output. As long as the power of the appliance does not exceed the power of the inverter, it can be used normally. 2. But we must also note that due to the use of the car's battery, the battery's loss of electricity is more serious, exacerbating the damage of the battery. In order to charge the battery as quickly as possible, the magneto will work harder and the vehicle will consume more fuel. The increase is related to the degree of your electricity use. Moreover, boiling water is actually equivalent to a large resistor, which generates high heat when the current passes through the resistor. This will cause more damage to the battery. So although it can be used to boil water, try not to do it as often as possib...

The report  Solar PV inverters – Update 2018  says that Asia Pacific, currently the leading market for solar inverters, with a market valued at £3.75b in 2017, will suffer the most and see its market share fall from 59%  to 38% in 2022. The Americas market is expected to grow from 27% to 41% and EMEA (Europe, Middle East, and Africa) will increase from 14% to 21% in  the period 2017 to 2022. Subha Krishnan, Power Analyst at GlobalData, said: “In terms of market value, China, the US, and Japan together held over 65% and led the global solar PV inverter market in the year 2017. The market developments in the top countries are largely due to economies of scale, emerging inverter technologies, and policy-based government and institutional industry.” Between 2017 and 2022, the global solar PV inverters market is expected to witness a negative compound annual growth rate (CAGR) of 10.15%, in terms of market value. The estimated fall of an avera...

Under normal circumstances, the thickness of the cable is designed and installed according to actual requirements. Take our current 12V 110V car power inverter 300W as an example. Most of the standard clip lines or cigarette tip lines in the market are 2.5 square meters. . It can carry 16A current. According to this calculation, it can carry the maximum power of 16X220=3520VA=3.52KW However, if inverter working at 300W full load, you will find that the power cord will become hot and soft, which will gradually weaken the load capacity. If the distance between the battery and the inverter is very long, in order to reduce the loss of the line caused by the current attenuation, and in order to avoid the above-mentioned problems, we need to replace more than 4 square copper wire. Of course, there are some inverters that do not use pure copper wires in order to reduce costs, or use the copper-clad aluminum wires, so we have to figure out when choosing them.

1.LED belongs to inductive load. The current LED string has a capacitor current limit. The capacitor is charged with about 300 volts DC during charging. This DC voltage and the 300 volts in the inverter are stacked in series to 600 volts. It is easy to put the withstand voltage at only 500-600 volts. Inverter output MOS tube breakdown. 2. Modified sine wave is also divided into two kinds, one is an ordinary, ordinary repair sine wave, just the square wave into a simple correction, one is a good, the other wave is a better correction. High quality repair sine wave with LED lights. Ordinary modified sine wave has many restrictions on the load, such as with resistive load (incandescent lamp, electric furnace (except induction cooker) and other loads) is no problem, but capacitive load (such as rechargeable LED flashlight) will appear on the edge of the pulse Inrush current causes capacitive load to be easily damaged when the modified sine wave power is supplied, and the work of induct...

The inverter is a DC to AC transformer. In fact, the converter is a voltage inversion process. The converter is to convert the AC voltage of the power grid into a stable 12V DC output, but the inverter is to convert the 12V DC voltage output by the Adapter to a high-frequency AC voltage; the same applies to the pulse widths used in both parts. Modulation (PWM) technology. The core part is a PWM integrated controller, Adapter UC3842, inverter uses TL5001 chip. TL5001 operating voltage range 3.6 ~ 40V, its internal error amplifier, a regulator, oscillator, PWM control with dead-zone control, low-voltage protection circuit and short circuit protection circuit. 1. Input interface part: Input part has 3 signals, 12V DC input VIN, working enable voltage ENB and Panel current control signal DIM. VIN is provided by the Adapter. The ENB voltage is provided by the MCU on the motherboard. The value is 0 or 3V. When ENB=0, the inverter does not work, while at ENB=3V, the inverter is in no...
