Modified sine wave Inverter

The modified sine wave are also called quasi-sine wave (or modified sine waves, analog sine waves, etc.). A modified sine wave is a kind of waveform between a sine wave and a square wave. The output waveform has a time interval between a positive maximum value and a negative maximum value, but the waveform of the quasi-sine wave is still a broken line. The modified sine wave switching inverter uses PWM pulse width modulation to generate the modified wave output. In the inverter process, the power loss of the system is greatly reduced due to the use of dedicated intelligent circuits and high-power FETs. And the soft start function is added to effectively ensure the reliability of the inverter. If the quality requirements for power consumption are not very high, and it can meet the needs of most electrical equipment, it still has 20% harmonic distortion, which will cause problems when running precision equipment, and will also cause high frequency to communication equipment. A modified sine wave inverter can be used for simple systems that don’t have any delicate electronics or audio equipment that may pick up the choppy wave and produce a hum. Old tube TVs and motors with brushes are usually ok with modified sine wave. Your digital clock will likely act funky, and battery rechargers quite often just plain won’t work. Some equipment may seem to be working fine, but may run hotter than with a pure sine wave and reduce the life of it.
