Abstract

The invention provides a dual-mode power supply circuit of a digital igniter, which can utilize a magnetogenerator to supply power for the digital igniter under the condition of insufficient jar voltage or bad contact. The dual-mode power supply circuit of the digital igniter comprises a power supply circuit, a capacitor charge and discharge circuit and a magnetogenerator voltage pulse distribution circuit, wherein the power supply circuit is used for receiving voltage pulse output by the magnetogenerator or the output voltage of a jar and outputting the working voltage of the digital igniter; the capacitor charge and discharge circuit is used for receiving the voltage pulse output by the magnetogenerator for charge and energy storage and discharging an ignition coil according to the ignition pulse signal of the digital igniter; and the magnetogenerator voltage pulse distribution circuit is used for receiving the voltage pulse of the magnetogenerator and respectively distributing the positive half cycle and the negative half cycle of the voltage pulse of the magnetogenerator to the power supply circuit and the capacitor charge and discharge circuit.

Description

technical field [0001] The invention relates to a power supply and energy storage circuit of a digital igniter, in particular to a power supply and energy storage circuit of a motorcycle digital igniter. Background technique [0002] At present, motorcycle igniters are transitioning from analog igniters to digital igniters, and the power supply of digital igniters is now generally powered by the battery that comes with the motorcycle. Due to the external conditions such as the motorcycle use environment, especially Due to violent vibration, it is easy to cause poor contact between the power supply cable and the battery, affecting the normal operation of the igniter, causing the motorcycle to suddenly lose power when driving at high speed, and easily causing safety accidents; moreover, when the motorcycle is not used for a long time, the battery Insufficient voltage, unable to ignite normally. When this happens, the driver is not easy to detect the specific location of the fa...
