Abstract: The invention relates to a capacitive battery active equalization circuit, including a battery pack, an equalizer set, an energy storage capacitor group, and a main control unit, the equalizer set comprises n equalizers; the adjacent equalizers are connected to each other through control signal interaction pins; the main control unit is connected with the control signal interactive pin of the first equalizer or the last equalizer in the equalizer set; the battery pack comprises n+1 batteries connected in series; the energy storage capacitor group includes n capacitors, and each capacitor is connected to the capacitor connection pin of the corresponding equalizer. The switching control module of the equalization chip is used to control the capacitor connection pin to selectively connect with high-voltage battery and low-voltage batteries so as to transfer power and effectively improve equalization efficiency.

Abstract: Diamond microtip field emitters are used in triode vacuum microelectronic devices, sensors and displays. Diamond triode devices having integral anode and grid structures can be fabricated. Ultra-sharp tips are formed on the emitters in a fabrication process in which diamond is deposited into mold cavities in a two-step deposition sequence. During deposition of the diamond, the carbon graphite content is carefully controlled to enhance emission performance. The tips or the emitters are treated by post-fabrication processes to further enhance performance.
