Aiming at the technical bottlenecks existing in the current warp knitting machine control system such as jacquard drive circuit, the design method of self-boosting power supply circuit integrated with jacquard driver is proposed for the embedded warp knitting machine jacquard control system for miniaturization design. The voltage boost circuit designed can boost the low voltage from the input of the working power supply to the high voltage for the output to drive the oscillation of the piezoelectric ceramic jacquard needles. Since the circuit adopts energy storage inductance instead of current-limiting resistor to optimize the driving circuit, it not only limits the forward charging current of the piezoelectric ceramic, but also effectively realize the energy recovery function. The effectiveness of the design method is verified by simulation. [ABSTRACT FROM AUTHOR] |
