What is the Power Inverters (1)?
Updated: 2013-12-10 01:28:58     (GOBRIGHT NEWS DEPT)

1. What's a power inverter? What's the purpose of power inverter?
Simply, power inverter is an electronic equipment, it can convert 12V (24V for diesel powered car) DC of automobile to 220V/50Hz AC. We usually use 220V AC to DC, but the purpose of the inverter power is contrary to it. We are in a "mobile" era, mobile office, mobile communications, mobile leisure and entertainment. In the mobile state, people not only need low-voltage DC supply by the battery, but also need a 220V AC in our daily life. Therefore, inverter can meet our needs.

2. According to the output waveform, the inverter is divided into several categories?

Mainly classified into two categories, one category is Pure Sine Wave Inverter, and the other is a Square Wave(Modified Sine Wave) Inverter. Output Pure Sine Wave Inverter with the grid we use every day, like alternating current sine wave or even better, because it does not exist in the electromagnetic pollution grid. Modified Sine Wave Inverter output is the square wave alternating current with poor quality, its positive maximum to negative maximum value almost produces at the same time; result in the inverter load and severe destabilizing influences. At the same time, its load is low, only 50-60% of rated load, not with inductive load (see under for further information). Carried load is too high, square-wave current contains three components will increase the flow of harmonics of the capacitive load current, even damage the load of the power supply filter capacitor. In response to these shortcomings, in recent years, a quasi-sine wave (or modified sine wave, sine wave amended, simulated sine wave, etc.) inverter appeared, its output waveform have a time interval from positive to negative maximum value, its applicable effect has improved, but the quasi-sinusoidal waveform is still formed by the perpendicular line. So, it is belongs to square wave category with poor continuity. In conclusion, sine wave inverter can provide high quality AC, which can carry any kind of load, but need the high technical and costs. Quasi-sine wave inverter can meet most of our demand for electricity, high efficiency, noise, moderate prices, so it has become mainstream products in the market. The production of square-wave inverter use the simple harmonic oscillator, its technical level is the 50's, will gradually withdraw from the market.

3. What’s Inductive load?
Generally, the application of the principle of electromagnetic induction produced by high-power electrical products, such as motors, compressors, relays, lamps and so on. This type of product needs starting current, which is much greater than the normal operation of a required current (about 3-6 times).For example, A normal operation refrigerator with 150-watt power consumption, the power to start up more than 1,000 watts. In addition, due to the moment of the inductive load connected to the power or disconnect it, will result in counter-EMF voltage, which is much larger than the peak voltage of the power inverter can bear. It is easy to cause the instantaneous inverter overload and affect the life of the inverter. Therefore, this type of electrical equipment needs a higher wave form.

4. Which electrical equipment does the Quasi-sine(Modified Sine) wave inverter can be used?
Quasi-sine(Modified sine) wave can be divided into several types from square wave to the rounded trapezoidal wave. We only discuss the square wave here, which is the wave form of the high-frequency inverter in the present market.

Such quasi-sine wave inverter can be applied to notebook computers, television sets, combined audio, video cameras, digital cameras, printers, all kinds of chargers, PDA, game player, DVD players, mobile DVD, Home Therapy, etc. , a larger output power inverter can also be applied to small electric appliances such as hair dryer, electric cup, kitchen appliances, etc.

But the type of inductive load appliances such as refrigerators, electric drills, etc. It is not suitable a long time the use of quasi-sine wave inverter for power supply. Otherwise, it would be damage the inverter and relate electrical products or shorten the expected service life. If you have to use inductive load, you can select a larger reserve capacity quasi-sine wave inverter, such as super peak power inverter provided by this website. Here, we take the quasi-sine wave inverter used in TV (the traditional display type) for example. TV has the following three requirements on the inverter: First of all, when turn on the TV; the degaussing circuit needs a great power in the moment, so need higher peak power requirement of the inverter. For example: a normal operation 25-inch digital color TV sets with 80W power consumption, and boot up to 1450W instantaneous power. Second, because the TV field frequency equals the frequency of the AC electric network, the AC inverter output frequency must be accurate. Third, the inverter should not interfere with TV. Even if it can meet the three conditions above, when use of quasi-sinusoidal AC , the screen will still have a few fixed interference pattern, the green color will be a slight bias (using the old-fashioned TV, the color cast is very serious), but the other is no different.
