In practical market application, the resonant ignition high-voltage pack circuit is independently used as an ignition module in a combustion control system and is matched with other modules (such as a central control module, an actuating mechanism, a fuel delivery module, an air delivery module and the like) for use. The method is mainly applied to industries such as industry, chemical industry, petroleum, natural gas and the like.
As shown in fig. 1, the first coil 41 constitutes a primary coil, the third coil 43 constitutes a feedback coil, the first capacitor C1 is a resonant capacitor, the second capacitor C2 is an electrolytic capacitor, the anode of the second capacitor C2 is connected to the output terminal of the fourth diode D4, and the cathode of the second capacitor C2 is connected to the input terminal of the fifth diode D5.
The basic working principle is as follows:
as shown in fig. 1, the resonant ignition high-voltage pack circuit is input in a half-wave rectification mode, commercial power is subjected to half-wave rectification through a diode D6, then is subjected to parallel current limiting buffering through resistors R3 and R4, and then charges a capacitor C4, the charging voltage of the capacitor rises continuously, and when the voltage exceeds the threshold value of a voltage stabilizing diode ZD1, a trigger triode Q1 is conducted. The charge stored in capacitor C4 charges the primary coils (P5-P7), and when the primary coil magnetic field reaches saturation, the feedback coils (P6-P8) generate reverse potential, and the reverse potential is applied to the base of the main power tube Q1, so that Q1 is cut off. When Q1 is turned off, since the resonant capacitor C1 is connected in parallel with the primary coil to form an LC oscillating circuit, the internal stored energy cannot be instantaneously discharged, and thus the remaining energy is output from the secondary coil by continuous oscillation.
And after the residual energy is released, the reverse cut-off voltage generated by the feedback coil returns to zero. At the moment, Q1 is triggered to be conducted by a voltage stabilizing tube ZD1 again, and the resonance process is started again after the conduction. And (3) continuously repeating resonance until the voltage value of the energy storage capacitor C4 is reduced to be lower than the threshold value of the trigger voltage regulator tube ZD1, pausing the resonance process, and repeating the above processes again until the charging voltage of the C4 after the half-wave rectification of the mains supply is higher than the threshold value of ZD1 again.
Because the threshold value of ZD1 is set to 100V, the saturated driving voltage of Q1 is about 6V, and the maximum voltage value of C4 after commercial power rectification is about 300V (DC), it can be seen that when the voltage value of C4 varies between 106V and 300V, the boost coil enters into the oscillation process, and when the voltage value of C4 is lower than 106V, the whole circuit enters into the pause state, and only C4 is charged. The whole high-voltage discharge process is intermittent resonance discharge.
The low-voltage dotted end of the output coil is connected to a commercial power zero line through piezoresistors ZR2 and R8 and is connected to the equipment shell, and the high-voltage dotted end is connected with a discharge needle. The piezoresistor and the R8 are connected to the zero line so as to ensure that the discharge arc is continuously stable and prevent no arc output.
