Embodiment 1

[0033] figure 2 Waveform diagrams showing alternate output pulses of a dual-energy solid-state modulator, image 3 A solid-state modulator for dual-energy pulse output is illustrated, which includes two DC power supplies for providing energy to energy storage capacitors; two pulse switches 1 . Among them, the first pulse switch 1 includes energy storage capacitors C1, C2, controllable switches Q1, Q2, the output end of the second pulse switch 1 is not connected in parallel with a diode, and the output end of the second pulse switch is connected in parallel with a diode D1, which is a controllable switch. Q1 and Q2 respectively provide trigger pulses to turn on Q1 and Q2 respectively; the output terminals of the two pulse switches are connected in series, and after series connection, the output terminals are connected in parallel with RCD absorption, and then connected in parallel with a pulse transformer.

Embodiment 2

[0037] Figure 5 It illustrates the relationship between the trigger pulse of another controllable switch and the output high and low energy pulses. The difference from Embodiment 1 is that the trigger pulse of Q2 is wider and can be turned on or off in advance. As shown in the figure, the controllable switch Q1 is triggered to be turned on at time t0, and is turned off at time t1. The modulator outputs a pulse voltage of V1 and a low-energy pulse of P1 with pulse energy. At time t2, the controllable switch Q2 is triggered to turn on, because Q1 is not triggered to turn on, and the pulse switch 1 is not connected in parallel with a diode, so no current path can be formed, and there is no voltage output; at time t3, Q1 is triggered to turn on, and the energy of the energy storage capacitor C2 passes through Q2, Then superimpose the energy of C1 to output energy through Q1 and the pulse transformer. The pulse transformer obtains the input voltage as the sum of the voltages at bo...

[0039] Figure 6It shows another main circuit of solid-state modulator to realize dual-energy pulse output, including DC power supply 1, DC power supply 2, and DC power supply 3 for providing electric energy for the energy storage capacitor; the first pulse switch, the second pulse switch, the third The pulse switch includes energy storage capacitors C1, C2, C3, controllable switches Q1, Q2, Q3, the output end of pulse switch 1 is not connected in parallel with diodes, and the output ends of pulse switch 2 and pulse switch 3 are connected in parallel with diodes D1, D2. When the controllable switch Q1 in the pulse switch 1 is turned on, the energy of the energy storage capacitor C1 outputs energy through Q1, pulse transformer, diode D1, D2, and the input voltage obtained by the pulse transformer is the voltage at both ends of the energy storage capacitor C1, and the output pulse voltage is V1, and the pulse energy is P1. When the controllable switches Q1, Q2, and Q3 in the pu...

Abstract

The invention relates to a solid-state modulator, which comprises a direct-current power supply, a plurality of pulse switches, a diode and a pulse transformer, wherein the output ends of the plurality of pulse switches are connected in series and then are connected with the input end of the pulse transformer; the pulse switch comprises an energy storage capacitor and a controlled switch, wherein the energy storage capacitor is connected with a direct-current power supply in parallel and is used for charging the energy storage capacitor; when the controlled switch in the pulse switch which is not connected with the diode in parallel is triggered to be switched on, the energy storage capacitor, the controlled switch, the pulse transformer and the diode form a current loop, and the input end of the pulse transformer obtains low-voltage pulse and correspondingly outputs low-energy pulse; and when the controlled switches in the at least one group of pulse switches which are not connected with the diodes in parallel and the at least one group of pulse switches which are connected with the diodes in parallel are triggered to be switched on at the same time, the input end of the pulse transformer obtains high-voltage pulses and correspondingly outputs high-energy pulses.

Description

technical field [0001] The present invention relates to a high voltage pulse modulator, especially a solid state modulator. Background technique [0002] The pulse modulator is essentially a power converter, which converts the AC power sent by the primary power supply into DC power of a suitable voltage, and then forms and controls the modulated pulse required on the load through the pulse generation system. The basic principle is to use The on-off state of the switch is used to control the pulse signal. Solid-state modulator is a type of pulse modulator, which is widely used in many fields such as national defense, industrial irradiation, food processing, medical treatment and pollution control.
