The difference between the modified wave and the pure sine wave of emergency portable power station

1. Different waveforms

The ability of pure sine waves is called sine waves. Modified sinusoidal wave is a kind of waveform between sinusoidal wave and square wave. Its output waveform is in the positive maximum to the negative maximum with a time interval, but the waveform of quasi-sinusoidal wave is still composed of broken lines, belonging to the category of square wave.

2. Different stability

Sine wave waveform is continuous, in the process of use is very stable, good performance. Corrected wave, waveform is composed of broken lines, can not use relatively sophisticated instruments, especially some medical equipment such as oxygen machine.

3. Different application scope

Sine wave has sine wave inverter, sine wave power inverter output is the same or better than the grid we use everyday sine wave alternating current, because it does not exist in the grid electromagnetic pollution.

Correction wave inverter, can be used in mobile phones, laptops, television, video cameras, CD players, all kinds of chargers, car refrigerators, game consoles, DVD players, power tools.
