With the development of flexible HVDC technology in the world, back-to-back HVDC system based on MMC topology have more attention. A high power back-to-back flexible HVDC prototype has been developed to assess performance and reliability of construction of converter valve segment. Valve normal working condition (rated conditions rated voltage, current, temperature), valve transient working condition (temporary overvoltage, overcurrent), valve fault protection and anti-interference ability are accessed. Performance and reliability of control and protection equipment are assessed. The design of control and protection strategy is optimized. The correctness of main circuit design is tested.

s. The electronic technology is a key component of digital high-resolution ADC converter. Currently based on comparative parallel ADC conversion time up to nanoseconds, and even nanosecond commercialization devices are also listed a large number with high price. This paper introduces an AD conversion based on the interpolation parallel series circuit. The working mechanisms are reported and the key circuit design is illustrated in details. The experiments are carried out in this paper for examining the circuit. The results show the good performance.

AbstractThe goal of this work was to investigate the capabilities of high-power microwaves in manufacture of small-grained barium cerate ceramics. Having compared the samples sintered in the microwave and the thermal fields, we inferred that the microwave sintering occurs at far higher rates. It is also noteworthy that microwave sintering provides a record-breaking low temperature of barium cerate sintering (900°C). Having studied the effect of a microwave field on the microstructure of sintering products, we found that high-power microwave processing significantly reduces the average grain size of barium cerate ceramics.
