Finally, because high - speed power solenoid valve is one of the most important executive parts in the electronic control diesel engine and the performances of diesel engine are strongly related to the solenoid valve, the response performance of the solenoid valve is investigated. the response performance of the solenoid is influenced by many factors, such as driving voltage, electric driving unit etc. in order to have high excitation voltage and in low maintaining voltage, a high - low voltage electric driving unit is designed, and in order to make the solenoid valve close more rapidly, an active free - wheeling circuit and a bootstrapping circuit are designed in the electric driving unit, too. in the high - low electric driving unit, high voltage and low voltage are supplied by the dc - dc device and by the accumulator respectively
高速強力電磁閥的響應性能除了與閥本身的結構和材料有關外，與驅動電壓、驅動電路的設計密切相關，本文通過分析，首先開發出一種高低壓驅動電路，高壓電源是山升壓式dc - dc原理獲取的，低壓由蓄電池本身提供，實現高壓強激和低壓維持的功能，電路中採用有源續流電柴汕機中卜軌知介系統的設訓及其七川j敝略的叭究路進行續流，加誣了電磁閥的關閉速度；採用自舉吐路，降低了場效應管對驅動電壓的要求。 -
Comparing with the ac - dc - ac converter, the commutation process of a matrix converter ( mc ) is more complicated due to having no natural free - wheeling paths
