The specific embodiment

As shown in Figure 1 and Figure 2, comprise power supply, input button, single-chip microcomputer, liquid crystal display circuit, three paths of independent booster circuit and impulse output circuit, power supply one tunnel output connects single-chip microcomputer running voltage end, another road output of power supply connects booster circuit, the outfan of booster circuit connects impulse output circuit, on input button, liquid crystal display circuit, three paths of independent booster circuit and impulse output circuit and the single-chip microcomputer separately corresponding interface be connected.The model that single-chip microcomputer U1 adopts is HT46R47, adopts 2ms regularly to interrupt as time-base signal, and single-chip microcomputer carries out output pulse width and FREQUENCY CONTROL, the control of high voltage control pulse frequency, various timing controlled and demonstration, and detailed process is seen software flow block diagram 3.

Above-mentioned booster circuit is by inductance L ₁, audion Q ₁₀, diode D ₇, charging capacitor C ₁Form inductance L ₁An end connect power supply, the other end connects audion Q ₁₀Colelctor electrode, audion Q ₁₀Grounded emitter, base stage connects corresponding output pin on the single-chip microcomputer, colelctor electrode connects diode D ₇Anode, diode D ₇Negative electrode connect charging capacitor C ₁Positive pole, charging capacitor C ₁Positive pole be connected to impulse output circuit, charging capacitor C ₁Minus earth.

When transistor Q10 conducting, power supply is to inductance L 1 energy storage, and inductive current increases, and induction electromotive force is that a left side is positive right negative, and diode D7 oppositely ends, and load is by capacitor C 1 power supply; When audion Q10 ends, inductive current reduces, electromotive force on the inductance L 1 is that the right side is just being born in a left side, energy discharges in the inductance, consistent with input voltage polarity, diode D7 conducting this moment, input voltage and induced voltage are simultaneously to capacitor C 1 charging, therefore the time charging voltage be input voltage and induced voltage and, therefore finished and boosted.Can reduce volume like this and overcome the problem of traditional transformer output circuit high frequency distortion, adopt the output transformerless high pressure output circuit that directly is coupled, the pulse deformity of having avoided transformer coupled formula output to produce can realize distortionless pulse output.

Above-mentioned impulse output circuit comprises two groups of symmetric power output loops, wherein audion Q ₁₂, Q ₁₃, Q ₁₆Be linked to be one the tunnel, audion Q ₁₂Base stage connect output pin corresponding on the single-chip microcomputer, grounded emitter, colelctor electrode is respectively through resistance R ₁₅Connect audion Q ₁₃Base stage, through resistance R ₁₆Connect audion Q ₁₆Base stage, audion Q ₁₃Grounded collector, audion Q ₁₃Emitter stage connect output electrode A, audion Q ₁₆Colelctor electrode connect output electrode B, audion Q ₁₆Emitter stage connect described charging capacitor C ₁Positive pole; Audion Q ₁₁, Q ₁₄, Q ₁₅Be linked to be another road, audion Q ₁₁Base stage connect output pin corresponding on the single-chip microcomputer, grounded emitter, colelctor electrode is respectively through resistance R ₁₃Connect audion Q ₁₄Base stage, through resistance R ₁₄Connect audion Q ₁₅Base stage, audion Q ₁₅Grounded collector, audion Q ₁₅Emitter stage connect output electrode B, audion Q ₁₄Colelctor electrode connect output electrode A, audion Q ₁₄Emitter stage connect described charging capacitor C ₁Positive pole.
