Three-phase inverter is converted AC voltage for three phases, namely AC380V, three-phase electricity is composed of three frequencies of the same, equal amplitude, phase in turn 120° alternating potential.

The definition of three-phase inverter is to convert DC power into AC power converter, its basic principle is SPWM, hardware architecture for four power modules composed of single-phase, three-phase bridge circuit, bridge output to the load between serial low-pass filter element, control loop has two signal generation sources, one is a fixed amplitude triangular wave (modulated wave) generator, #off grid inverters One is the sine wave generator, which uses the triangle wave to modulate the sine wave, and then it can get the square wave pulse column with the duty cycle changing according to the sinusoidal law. The modulation ratio is different, #inverter dc to ac and the number of a sine cycle pulse column is equal to the frequency of the modulated wave divided by the base wave frequency). #inverter for pv Then the square wave pulse train is used to control the above bridge circuit, and the sinusoidal voltage and current can be obtained on the output.
