The invention provides an ignition device, which comprises a pulse transformer circuit, wherein the pulse transformer circuit comprises a pulse transformer, a first controllable switch and a second controllable switch, the first input end of the primary side of the pulse transformer is externally connected with a direct-current power signal, the second input end of the primary side of the pulse transformer is externally connected with a pulse driving signal, the first secondary side is connected with the control end of the first controllable switch, the second secondary side is connected withthe control end of the second controllable switch, the first end of the first controllable switch is externally connected with a positive power supply, the first end of the second controllable switchis externally connected with a negative power supply, the second end of the first controllable switch and the second end of the second controllable switch are connected with an ignition coil and usedfor generating alternately-circulating voltage transformation pulse signals to supply power to the ignition coil. Through the implementation of the invention, the problems of low arcing circuit frequency and unstable arcing caused by unstable voltage transformation pulse signals are solved.
Description
technical field [0001] The invention relates to the field of spectrum technology, in particular to an ignition device. Background technique [0002] The arc discharge light source device is used to provide the excitation light source for the oil spectrometer to realize the precise determination of various trace elements in the oil. However, the excitation light source of the arc discharge light source device is mainly realized by arc discharge. However, the existing arc discharge circuit has problems such as low arc circuit frequency and unstable arc, which leads to the inability to fully excite the sample and affects the determination of trace elements. accuracy. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of low arc discharge circuit frequency and unstable arc drawing in the prior art, so as to provide an ignition device. [0004] To achieve the above object, the present invention ...
