inverter structure is based on a traditional two-level inverter unit

advantages:
1) The inverter structure is based on a traditional two-level inverter unit, so the main circuit topology is very simple.
2) The power unit adopts a modular structure, so all power units can be interchanged, maintenance is very convenient, and there are not a large number of clamp diodes or voltage balance capacitors in the circuit.
3) Each inverter bridge is powered by independent DC voltage sources, and there is no neutral point voltage imbalance.
In this paper, the high-Power Inverter Power Supply adopts multi-cell series technology, which combines the dual power control technology of single power unit with the horizontal phase shift PWM technology, which not only reduces the voltage level requirements of the switching device, but also satisfies the system's output voltage and The output power requirement has obtained a higher equivalent switching frequency than the simple multi-cell series technology, which greatly reduces the switching loss, further improves the output waveform, and reduces the harmonic distortion rate of the output voltage. Moreover, the power unit is The grid voltage is supplied by the phase-shifting transformer with multiple secondary sides, which has less harmonic pollution to the power grid and high input power factor. It is not necessary to use input harmonic filter and power factor compensation device.
