A flexible DC converter comprises a MMC and a DCPFC embedded within the flexible DC converter. The flexible DC converter features modularity and a flexible number of ports, enabling bidirectional control of DC power flow of two or more lines, addressing the issue of insufficient degrees of freedom in DC power flow control in meshed DC systems. The DCPFC is directly embedded in the flexible DC converter, allowing for energy balance without the need for external power sources and high-voltage isolation devices, with a wide range of power flow regulation. The control method can manage both internal and external energy balance of the device. Additionally, a main circuit parameter designing method can serve as a basis for selecting circuit components for the device. A fault protection strategy and an active fault current suppression method can enhance the reliability of the device under complex extreme conditions.

By means of heterologous expression of an aminotransferase and a malonyl-CoA reductase, an artificial synthesis pathway for synthesizing malonyl-CoA by using β-alanine (β-ala) as a precursor is constructed as follows: firstly, under catalysis of a transaminase, β-ala transfers amino groups to α-ketonic acid (such as pyruvic acid, oxaloacetic acid, or α-ketoglutaric acid, etc.), to form an intermediate product 3-oxopropanoate and a corresponding amino acid; the 3-oxopropanoate generates malonyl-CoA under the action of the malonyl-CoA reductase.

Provided in the present invention are a superconducting strip structure for improving the resistance of a superconducting constant-current switch, and a manufacturing method. The structure comprises conductive layers, a superconducting layer, a buffer layer and a substrate layer, wherein the substrate layer, the buffer layer and the superconducting layer are sequentially arranged in a stacked manner; and the face of the superconducting layer that faces away from the buffer layer comprises, along a strip, at least two conductive layers arranged spaced apart from each other, and a superconducting path for communicating the two conductive layers is arranged on the superconducting layer. The superconducting path is arranged on the superconducting layer between the two conductive layers, so that the current can only flow from one conductive layer to the other conductive layer by means of the superconducting path. Therefore, the characteristic of the superconducting layer, when in a non-superconducting state, presenting a relatively large resistance can be utilized, so that the whole superconducting constant-current switch presents a relatively large resistance. The switch has a small structure and is capable of performing fast switching. The resistance of the superconducting constant-current switch, when turned on, can further be increased by means of reducing the conduction cross-sectional area of the superconducting path and increasing the path length of the superconducting path.
