Abstract

The utility model discloses a solid -state electron gun power pulse modulator, its characterized in that: the modulator include that power module passes through pulse driving circuit and controls the discharge switch more than two and two respectively, realize pulse output through the discharge switch. Since the above structure is adopted, the utility model is simple in operation, has the reliability height simultaneously, small and impulse waveform degree of distortion characteristics such as little.

Description

A kind of solid-state electronic rifle power pulse modulator

Technical field

The utility model relates to the application of pulse technique, particularly a kind of solid-state electronic rifle power pulse modulator.

Background technology

Along with the development of pulse technique, all solid state power arteries and veins modulator extensively replaces hydrogen thyratron, vacuum-tube modulator.Overcome that hydrogen thyratron, vacuum-tube modulator preheating time is long, efficiency is low, volume is large, heavy, the life-span is short, poor stability, faultThe shortcoming that rate is high, cost is high.

What existing electron gun power pulse modulator adopted is input voltage through over commutation, filtering, boost to a tenteringThe DC level of value, then discharge by discharge switch, voltage is risen to the electricity needing through the pulse transformer of a hypermutation ratioPress. But waveform is more serious in distortion after the transformer of hypermutation ratio, simultaneously for the impulse modulation that needs dual intensity functionDevice, its whole control system and power unit are more complicated.

For the problems referred to above, a kind of novel power pulse modulator is provided, reducing pulse shape distortion degree is existing skillThe problem that art need to solve.

Utility model content

Technical problem to be solved in the utility model is, a kind of solid-state electronic rifle power pulse modulator is provided, and reachesReduce the object of pulse shape distortion degree.

For achieving the above object, the technical solution of the utility model is, a kind of solid-state electronic rifle power pulse modulator, itsBe characterised in that: described modulator comprises that power module controls respectively two and plural electric discharge by pulse driving circuitSwitch, realizes pulse output by discharge switch.

Described power module for be input as civil power AC220V after rectifying and wave-filtering by inversion and LC series resonance, connectReceive the elementary of charging transformer.

Described pulse driving circuit is that two groups of control enable signals have been selected or be difficult through the decoding of decoder to controlSystem drives the output of signal, controls Voltage-output amplitude.

Described discharge switch is made up of the IGBT discharge module of some, IGBT discharge module in the process of chargingAccess power module in parallel charges; IGBT discharge module discharged in series when electric discharge, output high voltage pulse.

The model that described decoder is selected is MC14543BCP.

A kind of solid-state electronic rifle power pulse modulator, owing to adopting above-mentioned structure, the utility model is simple to operate, withTime the features such as to have reliability high, and the little and pulse shape distortion degree of volume is little.

Detailed description of the invention

As shown in Figure 1, the utility model comprises that power module 1 controls respectively two and two by pulse driving circuit 2Above discharge switch 3, realizes pulse output by discharge switch 3.

In the utility model, power supply is a power module 1 independently, the IGBT module that discharge switch 3 is someComposition, charging has adopted charged in parallel, and electric discharge adopts the pattern of discharged in series, directly voltage is risen to required voltage amplitude,Voltage wave shape distortion degree is less, and pulse driving circuit 2 has adopted the mode of grouping that IGBT is divided into corresponding group of number, and each group is drivenMoving power supply separately, drive signal can regulate the output size of rifle potential pulse, thereby it is two to meet modulator by controlling theseThe requirement of energy. Comprise power supply, drive and control, three parts of discharge switch.

Power module 1, for being input as civil power AC220V, by inversion and LC series resonance, is connected to charging after rectifying and wave-filteringTransformer elementary, power acquisition is realized by the mode of frequency modulation, controls the driving side of power supply with respect to the pattern of determining frequency fixed widthFormula, has higher driving frequency, can reduce resonant inductance in series resonant tank and the profile of charging transformerSize, thus the volume of power supply reduced;

What drive circuit 2 adopted is to have selected or be difficult through the decoding of decoder with two groups of control enable signals to controlDrive the output of signal, thereby control the Voltage-output amplitude of solid-state electronic rifle pulse-modulator, control logic is simple to operation.Drive circuit 2 adopts two groups of control enable signals to select through the decoding of decoder or be difficult control to drive the defeated of signalGo out. Wherein, LD, the C of decoder connect high level, BI, PH, D ground connection, and what A, B connect is two path control signal, what output was used is d,E, f. Input can be inputted four kinds of states, controls four kinds of states of decoder output: three tunnels trigger all without, only open 1 tunnel triggering, open-minded2 tunnels are triggered and are opened 3 tunnels and trigger, and decoder are exported through one and door simultaneously, will drive signal and four kinds of output state phasesMerge, can export four kinds of different magnitudes of voltage, in actual operating process, only need to control the input state of decoderCan, simple to operate and controllability is strong.

Discharge switch 3 is made up of the IGBT discharge module of some, is altogether divided into four large groups, the driving power supply of four large groupsRelatively independent, in order to ensure that electron gun pulse-modulator has output, need to control three groups of drivings so drive only to control. ?Power supply storage capacitor charging of giving these modules in parallel in the process of charging, when electric discharge, these module discharged in series, thus formHigh voltage pulse. Adopt the voltage withstand class that can reduce in this way storage capacitor, switch is independent, defeated for the voltage of any demandGo out, only need to change the quantity of discharge switch, such mode is simple, and the volume of modulator is little simultaneously, does not need to usePulse transformer just can be realized required voltage requirement, also ensures that waveform is undistorted when having reduced cost.

By reference to the accompanying drawings the utility model is exemplarily described above, obviously the utility model specific implementation is not subject toThe restriction of aforesaid way, if the various improvement that adopted technical solutions of the utility model to carry out, or without improving directly applicationIn other occasion, all within protection domain of the present utility model.
