This article mainly introduces the characteristics of multi-functional bidirectional DC power supply products. The product uses three-phase p.f.C feedback design, the system adopts AC-DC and DC-DC bidirectional conversion two-level architecture, which can effectively stabilize the fluctuation of bus voltage during sudden increase, so as to improve the dynamic response time of the output of the whole machine, and at the same time electrically completely isolated.
The AC-DC bidirectional conversion adopts four-quadrant SVPWM technology, and the energy flows in both directions, and the power factor is as high as 0Above 99, the grid-connected harmonic pollution is small, 100% energy feedback, the feeder current pollution is small, and the input power factor is high: 099, harmonics 3% at rated operation.
In addition, the product also has intelligent monitoring function and a friendly man-machine interface, which can be controlled remotely via CAN bus or PC. At the same time, it also has the functions of constant voltage, constant current and constant power, and the voltage and current can be adjusted from 0-100% range, and the power supply load can be operated in dual mode. Compared with the traditional power supply, the maximum output voltage of the power supply far exceeds the rated value, and the power supply has a constant power output when the rated voltage is higher than the rated voltage, which maximizes the output capacity of the power supply.
In addition to the above features, the product also adopts advanced control algorithms and protection strategies to ensure its safe, stable and reliable operation. At the same time, it also has a wide operating temperature range and the ability to adapt to various environments, which is suitable for applications in various fields.
To sum up, the multi-functional bidirectional DC power supply product has the characteristics of high efficiency, stability, reliability and intelligence, and is an excellent power electronic equipment, which can meet the needs of various high-end applications.
