Step Wave Inverter

This kind of inverter output AC voltage waveform is the step wave, the inverter realizes the step wave output also has many different lines, the output waveform ladder number difference is very big. The advantage of step-wave inverter is that the output waveform is better than the square wave, the higher harmonic content is reduced, and the output waveform can realize the quasi sine wave when the ladder reaches more than 17. When using no transformer output, the machine efficiency is very high. The disadvantage is that the ladder-wave superposition circuit uses more power switch tubes, some of which also require multiple sets of DC power input. This brings trouble to the grouping and wiring of solar cell matrices and the balanced charging of batteries. In addition, stepped-wave voltages still have some high-frequency interference with radios and certain communications devices.
