The waveforms of inverters mainly include sine wave, square wave, modified sine wave, triangular wave and other types, each waveform has its own characteristics and applicable scenarios.
Sine wave is the waveform closest to the mains, with strong stability, low basic noise, wide adaptability and other characteristics, suitable for household appliances, medical equipment, precision instruments and some occasions with strict requirements for power quality, but the cost is high and the design is complex.
The output voltage waveform of the square wave inverter is a rectangular wave, which is characterized by high switching frequency, low cost, and low noise. Because it contains a large number of harmonic components, it is easy to cause instantaneous temperature rise of electronic equipment and cause harm to electronic devices, and is not suitable for equipment that requires high precision in power supply.
The shape of the waveform output by the corrected sine wave inverter is similar to that of the sine wave, but it is less than the sine wave, which can reduce the starting current required by the motor and other equipment when starting, prolong the life of the equipment, and is suitable for some equipment with high requirements for power quality.
The output voltage waveform of the triangle wave inverter is a triangle wave, which has the advantages of simplicity, low cost, and small voltage drop, but due to the low frequency of the output waveform, it is not suitable for equipment that requires high precision in power supply.
In general, various waveform inverters have their own advantages and disadvantages, and when choosing an inverter, it is necessary to determine the most suitable waveform type according to the specific application scenario and equipment requirements.
