Abstract: A phase-loss control method for a three-phase three-wire converter and a three-phase AC control system are disclosed. The processor executes this method by receiving a power signal, determining if the power signal has a phase loss, and determining whether the power signal had the phase loss at the previous moment. If there was no phase loss at the previous moment, it switches from a second operating state to a first operating state, outputting a first drive signal. If there was a phase loss at the previous moment, it switches from the first operating state to the second operating state, outputting a second drive signal. By detecting phase loss, the system can immediately switch between the first and second operating states based on whether phase loss is present or not, without causing the three-phase converter to shut down. This method allows seamless state switching, improving system stability.

Abstract: A preparation method of tungsten-rhenium-based diffusion-type thermionic cathode material containing low melting point barium calcium aluminate salt is provided, which relates to the field of preparation technologies of electron emission cathode materials. In the tungsten-rhenium-based diffusion-type thermionic cathode material prepared by combining freeze-drying and heat treatment, tungsten and rhenium elements are distributed evenly, and only a single phase exists in W—Re alloy powder after heat treatment.
