1. The transformation of single-phase electricity into three-phase electricity requires an increase in voltage, which can be achieved through an inverter, which is a device that can directly change the current and convert direct current into alternating current. It is called an inverter. This product device can convert AC 220V to AC 380V, which is also a relatively easy way to operate. Because it has a circuit and a microprocessor to control the circuit, it adds PWM modulation technology. Through the microprocessor, it can control six high-power crystals, and then import and output them in turn in the form of three-phase sine waves, becoming three-phase alternating current.
2. The second method is achieved through a unidirectional frequency converter, which is also a commonly used method. If the first method is used, an inverter is required. In the absence of this, it can be achieved in this way. It needs to adopt a triangular connection method, which works similarly to an inverter and can change the mains power to three-phase power.
