Portable battery generators all have inverters, but there are also differences in inverters. Today, I will show you the difference between pure sine wave inverters and modified sine wave inverters.
The output waveform is different
Pure sine wave inverters generally use PWM to invert, and some even add multi-step inverters. The structure is complex, but the output waveform is good, and it is suitable for inductive loads and capacitive loads. Modified wave inverters generally use square wave inverters, and a few add step inverters. The structure is simple, but the output waveform is poor, so it is not suitable for inductive loads and capacitive loads.
There is a gap in efficiency
Compared with the modified wave inverter, the pure sine wave inverter has higher efficiency, stable sine wave output, high frequency technology, and is suitable for various loads.
different applicability
The pure sine wave inverter is suitable for inductive loads, capacitive loads and resistive loads, and the modified wave inverter is only suitable for resistive loads. If the modified wave inverter is used on inductive electrical appliances, it will emit a lot of noise, and The loss of electrical appliances is also very large.
Therefore, for friends who want to buy a portable battery generator, they must choose a pure sine wave inverter, so that the waveform can be comparable to that of the mains and provide a strong guarantee for the safety of electrical equipment.
