Embodiment Construction

[0028] A three-phase current source type power supply and load integrated control system, including: ① current source type three-phase bridge, ② drive circuit, ③ voltage and current detection unit, ④ A / D conversion unit and ⑤ main control unit. The voltage and current detection unit collects the two-phase voltage signals of the AC busbar and the current signal of the DC busbar in the current source type three-phase bridge, and converts the collected two-way voltage signals and one-way current signal through the A / D conversion unit into The digital signal is transmitted to the main control unit through serial communication. The main control unit equates the current source type three-phase bridge into a buck / boost circuit, and adopts the duty cycle calculation method of controlling the instantaneous value of the DC inductor L current by the equivalent voltage vector to replace the traditional current vector method, and generates PWM through the voltage vector Wave, to control th...

Abstract

The invention discloses a three-phase current source type power supply and load integrated control system. The system includes: a current source type three-phase bridge, a drive circuit, a voltage and current detection unit, an A / D conversion unit, and a main control unit; the voltage and current detection unit collects two phases of the AC bus in the current source type three-phase bridge The voltage signal and the current signal of the DC bus; the A / D conversion unit converts the collected voltage and current analog signals into digital signals, which are serially sent to the main control unit; the main control unit adopts a DSP chip, and according to the collected voltage , The current signal and control requirements generate PWM waves to control the on-off of the switch tube. This system uses the method of equivalent voltage vector control of the instantaneous current value of the DC inductor to replace the traditional current vector control strategy. This method has many advantages: according to the voltage of the DC side, the instantaneous control of the DC side current can be carried out. This control method The current control under the control only needs the current sensor on the DC side.

Description

technical field [0001] The invention relates to a new three-phase current source type power supply and load integrated control system. Background technique [0002] DC power supply and load device is a core device to realize energy conversion and diversified applications. It is widely used in all walks of life, from power adapters, switching regulated power supplies to DC power transmission and distribution systems. With the rapid development of power electronics and control technology, the functional requirements for DC power supplies and loads have begun to diversify, and the requirements for characteristics have become higher and higher. In particular, the demand for high-performance DC power supply systems and electronic load systems has become wider and wider. A system that can be used as both a DC power supply and an electronic load is called an integrated power supply and load system. [0003] The traditional three-phase current source integrated power supply and loa...
