Battery-free manual ignition device and ignition method

Abstract

The invention discloses a battery-free manual ignition device and an ignition method, relates to the technical field of AC-AC converters and high-voltage arcing, and provides AC-AC converter topology.A converter is based on an alternating current high frequency chopper capable of working in both a positive half cycle and a negative half cycle, and can directly convert low frequency alternating current generated by a manual generator into high frequency alternating current without a rectification link. The battery-free manual ignition device consists of the manual generator, the AC-AC converter, a Tesla coil, a high-voltage arcing gap and a high-frequency pulse generator. Chopper topology capable of normally working in the positive half cycle and the negative half cycle is formed by cooperation of a dual-switch structure and a primary part of the Tesla coil, low-frequency voltage generated by the generator can be directly converted into high-frequency voltage, and so the problem that the frequency of the manual generator is low and the frequency required by the Tesla coil is high is solved.

Description

technical field [0001] The invention relates to the technical field of AC-AC converters and high-voltage arcing, and is mainly used in the generation of various high-voltage electric sparks and gas ignition, and specifically relates to a battery-free manual ignition device and an ignition method. Background technique [0002] At present, liquefied petroleum gas (coal gas) is basically used in kitchen fires, which brings great convenience for family fires. Commonly used ignition tools for gas stoves are piezoelectric igniters and electronic igniters. Piezoelectric igniters are gradually being eliminated due to low efficiency and poor reliability, and electronic igniters have become the mainstream ignition equipment. Electronic igniters need batteries to provide energy, which brings two problems: 1. Batteries are highly polluting materials, and their use is contrary to the green and low-carbon social environment advocated by our country; 2. Batteries have limited power supply...

Piezoelectric igniters are gradually eliminated due to low efficiency and poor reliability, and electronic igniters have become mainstream ignition equipment

Electronic igniters need batteries to provide energy, which brings two problems: 1. Batteries are highly polluting materials, and their use is contrary to the green and low-carbon social environment advocated by our country; 2. Batteries have limited power supply life and insufficient safety, which leads to Users (especially large kitchens with frequent ignition) often affect the meal because the battery is dead when using it, and even for convenience, the user directly uses an open flame, which poses a safety hazard

However, these measures did not solve the contradiction between the low frequency of the manual generator and the high frequency required by the transformer
