Can single-phase electricity be converted into three-phase electricity?

Of course, the answer is yes, because the output of three-phase electricity is 380V and that of single-phase electricity is 220V, so we can realize the conversion from single-phase electricity to three-phase electricity by pressurizing the voltage output and increasing the frequency. Of course, this thing is difficult for ordinary people to realize, but there are such devices on the market. As long as you buy a single-phase to three-phase electricity equipment, you can realize the output of single-phase electricity to three-phase electricity.

Want to know whether single-phase electricity can be converted into three-phase electricity? First of all, we need to know their definition:

1.？ Single-phase electricity is a form of transmission composed of a single live wire and a zero wire, and the single-phase voltage is 220 volts. If necessary, there will be a third wire (ground wire).

2.？ Three-phase electricity is a power supply composed of three alternating potentials with the same frequency, equal amplitude and phase difference of 120. A generator that can generate an electric potential with equal amplitude and frequency and a phase difference of 120 is called a three-phase generator. A circuit powered by a three-phase power supply is called a three-phase circuit. U, V and W are called three phases, and the phase-to-phase voltage is line voltage with a voltage of 380 V. The phase voltage between the phase and the center line is called phase voltage with a voltage of 220 V.

The difference between single-phase electricity and three-phase electricity;

1. The power generated by the generator is three-phase, and each phase of the three-phase power supply and its neutral point can form a single-phase loop to provide power for users. Note that the AC circuit here can't be called positive or negative, but should be called line end (called live line for civil electricity) and zero line (called zero line for civil electricity).

2. Three-phase electricity is used in industrial production, and its voltage is 380 V; Ordinary residents use monophasic electricity in their lives, with a voltage of 220V V V.

Now that we know the definitions of single-phase electricity and three-phase electricity, and the differences between them, let's talk about the conversion from single-phase electricity to three-phase electricity: the introduction of single-phase to three-phase electricity power supply, the adoption of AC -DC- AC circuit structure, and the use of SPWM modulation control technology to convert ordinary single-phase electricity into industrial three-phase electricity. The three-phase power supply converted from single-phase power supply to three-phase power supply is a standard sine wave with a phase angle of 120 and a harmonic distortion rate of less than 2%, which fully meets the national three-phase power quality standard and is suitable for various types of loads. Single-phase to three-phase power supply solves the inconvenience caused by three-phase power shortage in some areas, and also solves the demand that some users can not handle three-phase power consumption due to site restrictions.
