Working principle

The is a device that converts direct current (DC from storage battery, solar and wind power) into alternating current (AC). It consists of bridge, control logic and filter circuit.

This use high-frequency power conversion technology, and use the ferrite transformer instead the old bulky silicon steel transformer. That is why this power is ligher, smaller than other similar. And the output waveform is pure sine wave.

Classification

1.Pure sine wave

It outputs pure sine wave alternating current that is the same as or better than the grid we use every day, because it does not have electromagnetic pollution in the grid. The sine wave provides high-quality alternating current and can drive any kind of load, but the technical requirements and cost are high.

About inductive load

In layman's terms, that is, high-power electrical products made using the principle of electromagnetic induction, such as motors, compressors, relays, and so on. This type of product requires a starting current that is much larger (approximately 5-7 times) than the current required to maintain normal operation. For example, a refrigerator that consumes about 150 watts during normal operation can have a starting power of more than 1,000 watts. In addition, because the inductive load generates a back electromotive force voltage at the moment of turning on the power or turning off the power, the peak value of this voltage is much larger than the voltage value that the can withstand, and it is easy to cause the transient overload of the, Affecting the service life of the. Therefore, this type of electrical appliance has higher requirements on the power supply waveform.

How to select

In addition to power and waveform, selection is also very important to choose the efficiency of the. The higher the efficiency, the less energy is wasted on the and the more electricity is used for electrical appliances, especially when you use small The importance of this point is more obvious when power systems.

Efficiency

It consumes some power when working, so its input power is greater than its output power. efficiency is the ratio of output power to input power. If an inputs 100 watts of DC power and outputs 90 watts of AC power, then its efficiency is 90%.

Continuous output power, peak output power

Some electrical appliances or tools that use electric motors, such as refrigerators, washing s, and electric drills, require a large current to drive at the moment of startup. Once the startup is successful, only a small current is needed to maintain their normal operation. Therefore, for the, there is the concept of continuous output power and peak output power. The continuous output power is the rated output power; the general peak output power is twice the rated output power. It must be emphasized that some electrical appliances, such as air conditioners and refrigerators, have a starting current equivalent to 3-7 times the normal operating current. Therefore, only s that can meet the peak power of electrical appliances can work normally.

How to choose the right inverter for your TV

TV sets have the following three requirements for s

1) First, when the TV is turned on, the degaussing circuit has a huge instantaneous demand for electrical energy, so the peak power of the is very demanding. For example, the power consumption of a 25-inch digital color TV under normal working conditions is about 80 watts, and the instantaneous power at startup is as high as 1450 watts.

2) Secondly, because the field frequency of the TV set is equal to the AC grid frequency, the frequency of the output AC must be accurate.

3) Third, the should not interfere with the TV. Even if the above three conditions are met, when the TV uses non-pure sine wave AC, the screen will still have a few fixed interference patterns, and the color will be slightly greenish (when using an old TV, the color cast is more serious).
