Device for controlling ignition and quenching by trigger circuit

Abstract

The invention relates to a device for controlling ignition and quenching by a trigger circuit, which comprises a second capacitor and a triode. The device is characterized in that one end of the second capacitor is connected with a fifth line, the other end thereof is connected with a fourth line and synchronously connected to a triggering end of the triode in parallel, a collector electrode of the triode is connected with a first line, and a discharge electrode is connected with a primary level of a transformer. The device for controlling ignition and quenching by the trigger circuit has the functions that a switch is controlled by utilizing a low voltage and meanwhile a positive electrode power supply can be switched off.

Description

technical field [0001] The invention relates to a flameout control device of a motorcycle igniter, in particular to a trigger circuit controlled ignition and flameout device. Background technique [0002] The flameout control of the motorcycle DC igniter adopts a high-voltage short-circuit structure to the ground, such as the first capacitor in the drawing of the manual, and a flameout line is connected at this position, and the capacitor cannot store electric energy through the short circuit of this line, so as to achieve control The role of motorcycle high-voltage ignition output, this structure is simple, but there are obvious shortcomings: 1. Although the capacitor cannot store electric energy, the first line of the transformer is connected to the positive pole of the battery for a long time, so that when the igniter does not work, the battery is always The discharge of the transformer will cause the battery to lose power and the transformer to be damaged. 2. Because th...

Although the capacitor cannot store electric energy, the first line of the transformer is connected to the positive pole of the battery for a long time, so that when the igniter does not work, the battery is always Discharge the transformer, resulting in battery loss and damage to the transformer

2. Because the voltage of the first capacitor is about 400V, using short circuit to control the flameout will cause the contact point of the flameout switch and the main switch to be coked due to the action of the arc, resulting in poor contact and difficult flameout failure
