Home > News & Events divided by the output waveform, the inverter is divided into several categories?

Answer: The two main categories, one category is sine wave inverter, and the other is a square wave inverter. Sine wave inverter output is the same as our daily use grid AC sine wave or even better, because it does not exist power of electromagnetic pollution. Square wave inverter output is the poor quality of the square wave alternating current, the positive maximum to the negative maximum value almost at the same generation, so that the load and the inverter itself cause severe destabilizing effect. Meanwhile, the load capacity is poor, only 40-60% of the rated load, not with inductive load (explained in detail below article). If the load carried by too large, square-wave current third harmonic components contained in the capacitive load will flow into the current increases, and in severe damage to the load of the power supply filter capacitor. For these shortcomings, in recent years a quasi-sine wave (or modified sine wave, modified sine wave, sine-wave, etc.) inverter, the output waveform from the positive to the negative maximum value between the maximum value of a time- intervals, using the results improved, but quasi-sinusoidal waveform is still the polyline, is a square wave areas, good continuity. In conclusion, sine wave inverter providing high-quality alternating current, can bring any kind of load, but the technical requirements and costs are high. Quasi-sine wave inverter can meet most of our electricity demand, high efficiency, low noise, moderate prices, and thus become the market mainstream products. Square wave inverter fabricated using a simple multivibrator, its technology is the level of the 1950s, will gradually withdraw from the market.
