System principle:
The inverter power supply after AC→DC→AC conversion is called single-phase to three-phase power supply, which is different from the variable used for motor speed regulation.Frequency control controller. The main function of the single-phase to three phase power supply is to convert the existing AC grid 220V into three-phase 380V power.Electric sine wave power supply. The ideal AC power supply is characterized by stable frequency, stable voltage, internal resistance equal to zero, and pure voltage waveform. Sine wave (no distortion). The inverter power supply is very close to the ideal AC power supply, so it can completely replace the remote area or cannot apply.Please ask for the three-phase area, but the output power of the single-phase to three phase power supply is determined by the 220V current of the mains. DZW series Phase-to-phase three-phase power supply, with microprocessor as the core, MPWM mode, designed with active component IGBT module, adopted Digital frequency division, D/A conversion, instantaneous value feedback, sinusoidal pulse width modulation and other technologies, so that the stand-alone capacity can reach 400KVA,Isolation transformer output to increase the stability of the whole machine, with strong load adaptability, good output waveform quality, easy operation and volume Small, light weight and other features, with short circuit, over current, overload, overheating and other protection functions to ensure reliable operation of the power supply.
Introduction:
Single-phase three-phase power supply, general-purpose direct / direct-current circuit structure, SPWM control technology used, general single-phase three-phase power for industrial use. Single-phase conversion three-phase power conversion after three-phase power standard sine wave, phase angle 120 °, tsunami loss rate small 2%, full-fledged national three-phase power mass standard, application in various types. Single phase three-phase power supply solution for three-phase electric power supply due to inconvenient three-phase electric power production, inconvenient, three-phase electric power supply demand for three-phase electric power supply.
