Beneficial effect is:
(1) centralized main resonance inductance: charging/isolation resistance Rn, R14+n and storage capacitor Cn forms RC charge circuit；
Storage capacitor C1~C14, snowslide pipe V1~V28, capacitance C15 and external loading form avalanche and discharge circuit (hereafter together
Abbreviation main circuit)；Resistance storage capacitor charge when from metering function, the excessively high charge cycle that will lead to of resistance value is long, reduce work
Repetition；In main circuit avalanche and discharge, resistance R1-R28 plays a part of that charge/discharge circuit is isolated；Select inductance relative to LC
(L29 ratio L1-L28 inductance value is several greatly by distributed resonant inductance L1~L28 in resonance feeding classification much smaller inductance L29
The order of magnitude) it is together in series and plays resonance step-up；And the inductance value that inductance L1-L28 is isolated is smaller (air core inductor), resonance
Its inductance can be ignored when charging, in main circuit avalanche and discharge, serve as isolation inductance, increases main circuit and charges back
The isolation on road.When main circuit avalanche and discharge, bias voltage Vb passes through main resonance inductance, isolation resistance/inductance and snowslide crystal
The circuit LR of pipe composition is discharged over the ground, but since the electric current of inductance cannot be mutated, the collector current of avalanche transistor can only be by
Zero start exponentially increase, and its current value be far below no current-limiting resistance when LC resonance feeding classification, to guarantee
Snowslide pipe it is more reliable exit avalanche condition.Simultaneously as inductance is smaller, the volume of circuit can be substantially reduced, more compact.
(2) half modulation feed: shown in bias voltage Vb such as Fig. 4 (E), identical charging electricity is fed with LC resonance to reach
Pressure, bias voltage are slightly above the latter's Δ V (usually in VCBO(the snowslide threshold voltage in triode V1, V15)/100 amounts
Grade).It need to only guarantee that power supply terminal voltage signal is ahead of the Ultra-short pulse voltage signal of first storage capacitor input in timing
Time be greater than time (t3-t2 in Fig. 4) of the primary complete resonant charging of any one RC charge circuit, then triggered in first time
Before pulse arrives, bias voltage on storage capacitor C1-C14 can resonance to close to VCBO, increase circuit in triggering arteries and veins
Rush the reliable trigger for the first time when intensity is lower, bias voltage is lower and hot operation.
(3) actively fuse mechanism: being added in the RC charge circuit (Fig. 1) has the thin of suitable resistance value and power bearing ability
Film resistance (R1-R28) (small in size, Surface Mount installation, consistency is good, and flat power bearing ability is low).The introducing of resistive elements causes
Charge efficiency is slightly lower compared with LC resonance feed, but when certain level-one in circuit or multistage avalanche transistor damage, due to electricity
The metering function and fuse protection of resistance act on, and snowslide pipe will not fuse open circuit, and the output of main circuit only can accordingly reduce (reduction width
Degree is positively correlated with transistor damage series).Meanwhile resistance addition so that when main circuit avalanche and discharge and charge circuit every
Increase from degree, the output amplitude of main circuit can also increased.
