Three-phase inverter is the conversion of the ac voltage phase, namely AC380V, three-phase electricity is made up of three same frequency, amplitude, phase difference of 120 ° to each other in turn equal exchange of electric potential.Is the definition of a three-phase inverter converts dc to ac power converter, the basic principle of SPWM , hardware architecture of four power module of single-phase, three-phase bridge type circuit, bridge between the output and load combination of low-pass filter element, the control circuit has two signal source, a triangular wave is fixed amplitude modulation wave generator, a sine wave generator, Sine wave to make use of the triangle wave modulation, can get the duty ratio according to the sine law of change of column, square wave pulse modulation ratio is different, a sinusoidal periodic frequency divided by the number of columns equal to the modulation wave pulse gib frequency). With a square wave pulse to control the bridge circuit, were given on the output meets the requirements of the sinusoidal voltage and current. Application fields include medium-sized IDC data exchange center rooms, medium-sized network management systems, billing centers, bank/securities settlement centers, industrial process control applications, and flow control fields. Provide stable, reliable, and safe solutions for small photovoltaic power generation systems such as homes, islands, and ships1.Low battery voltage input, three inputs and three outputs, support 50/60Hz power grid self-recognition; 2.Support three-phase unbalanced load, triple peak power, pure sine wave output; 3.Ultra-wide input voltage immunity range, adapt to harsh grid environment; 4.Built-in PWM or MPPT solar controller; 5.
