Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but embodiment of the present utility model is not limited to this.
The firing circuit with flash for prompting function described in the utility model, comprises and exchanges multiplier stage and sparking output stage, described interchange multiplier stage is connected by high-voltage line is corresponding with low-voltage line with sparking output stage, described low-voltage line ground connection; Described interchange multiplier stage is made up of multiplication of voltage electric capacity and half-bridge circuit in parallel, and described half-bridge circuit is made up of first diode of connecting, the second diode, and described multiplication of voltage electric capacity is made up of first electric capacity of connecting, the second electric capacity; The common port of described the first diode and the second diode, the first electric capacity and the second electric capacity is connected with input live wire end and input zero line side respectively; Described sparking output stage is made up of transformer, charging paths and RC branch road, described RC props up route and is connected on the first resistance and the 3rd electric capacity composition between high-voltage line and low-voltage line, described the 3rd electric capacity connects low-voltage line, described charging paths is made up of silicon-controlled device and two-way avalanche diode, described two-way avalanche diode is connected between silicon-controlled device base stage and the first resistance and the 3rd electric capacity common port, the emitter and collector of described silicon-controlled device connects respectively low-voltage line and transformer primary side first input end, and transformer primary side the second output connects high-voltage line; Also comprise flash for prompting circuit, described flash for prompting circuit is made up of the delay electric capacity and the light branch road that are connected in parallel on compared with between electronegative potential sparking electrode and low-voltage line, and described light props up Zener diode, light emitting diode and the first current-limiting resistance composition of route series connection.
From AC input to input power frequency 220V civil power, after the half-bridge voltage-multiplying circuit multiplication of voltage rectification that are formed by the first diode D1 and the second diode D2 and the first capacitor C 1, the second capacitor C 2, in the upper end of the first capacitor C 1, high-voltage line can obtain the DC voltage of 500V left and right, considers loss in reality in theory, can obtain DC voltage more than 400V, accordingly, D1, D2, C1, C2 should select the withstand voltage device of the above-mentioned high pressure of ability.
