The main circuit and control circuit of the three-phase power supply are designed based on three independent single-phase power supplies. The main circuit employs a rectifier-inverter configuration, including components such as rectifiers, DC filters, inverters, AC filters, and transformers. The rectifier section is a bridge rectifier, which is soft-started through an AC contactor and filtered by electrolytic capacitors to provide a stable current. The three single-phase inverter circuits output with a 120 electrical degree phase difference, ensuring electrical independence at the transformer's primary side. On the secondary side, they are connected in a star configuration to output the required three-phase AC power. Voltage and waveform control for single-phase output utilizes three independent single-phase controllers, allowing any phase of the three-phase power supply to be used as a standalone single-phase supply and to accommodate any unbalanced load, significantly enhancing the power supply's load adaptability. Other manufacturers cannot technically achieve such load unbalancing.
