  • Publication number: 20240429711
    Abstract: The disclosure discloses a magnetic bias active suppression method and system of a hybrid distribution transformer, whether the HDT is closed or not is judged based on the grid-side current, and accordingly smooth switching of the two sets of control strategies is achieved; excitation currents of an HDT main transformer and an isolation transformer are calculated based on a magnetic potential balance principle, and nonlinear feedback is performed, and the excitation currents are superposed after an original control instruction of an HDT converter, so that magnetic bias suppression is realized on the basis of ensuring an HDT grid-side current and load voltage control function. According to the system, a complex and expensive iron core magnetic flux sensor does not need to be additionally arranged, and the DC magnetic bias of the HDT under any working condition can be eliminated while the basic control function of the HDT is not affected.

  • Patent number: 11735903
    Abstract: A method for suppressing magnetizing inrush current of the transformer with flux linkage control includes connecting a small-capacity direct current/alternating current (DC/AC) converter with the secondary winding or auxiliary winding of transformer, detecting the primary side phase voltage before closing load, inducing the core flux linkage reference according to the relationship between the winding voltage and core flux linkage. The core flux linkage closed-loop PI control system is constructed to control the converter voltage in the synchronous coordinate, then the core flux linkage can track its reference with no static error, thus the sinusoidal flux linkage with 90-degree difference from the grid voltage can be pre-established in the core before no-load closing. By these methods, no matter when the main transformer closes, the core flux linkage is always in the steady state, and the magnetizing inrush current can be eliminated completely.

  • Publication number: 20230076949
    Abstract: The present disclosure provides a bisulfite-free, long-read, base-resolution method named long-read TAPS (lrTAPS) for detecting 5-Methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) in a nucleic acid sequence. lrTAPS comprises mild enzymatic and chemical reactions to detect 5mC and 5hmC, the two major epigenetic marks found in the mammalian genome, quantitatively at base-resolution without affecting unmodified cytosine.

The converter side windings and the control windings are respectively connected with the converter by the star connection with neutral point. Leakage magnetic cores are respectively inserted between the primary windings and the control windings or between the converter side windings and the grid side windings, so as to achieve magnetic integration design of the transformer and output connection inductor of the converter.

  • Publication number: 20220275424
    Abstract: This disclosure provides methods for cost-effective bisulfite-free identification in DNA, including whole genomic DNA, of the locations of one or more of 5-methylcytosine, 5-hydroxymethylcytosine, 5-carboxylcytosine and 5-formylcytosine. The methods described herein are based on the conversion of modified cytosine (5mC, 5hmC, 5fC, 5caC) to dihydrouracil (DHU), for example by TET-assisted pyridine borane treatment, followed by endonuclease cleavage of the DHU, and identification of the cleavage site, which corresponds to the location of the modified cytosine.

  • Patent number: 10968110
    Abstract: A method for preparing titanium-containing molecular sieves include the following steps: irradiating a mixed solution containing a silicon source, a template and a titanium source by a light source containing ultraviolet light before crystallization, and then subjecting the mixed solution to crystallization and post-treatment to obtain the titanium-containing molecular sieve. In the method for preparing titanium-containing molecular sieve of the present invention, the mixed solution containing the silicon source, the template and the titanium source is treated with the ultraviolet light, and free radicals generated by the ultraviolet light can effectively dissociate titanium oligomers and accelerate the hydrolysis of the silicon source, and thus match the hydrolysis rate of a silicon-titanium precursor, thereby preventing a titanium monomer from self-polymerization to form non-framework titanium.
