Compound mode solid pulse source

Abstract

The invention discloses a compound mode solid pulse source. The compound mode solid pulse source comprises a power system, a control system, a signal conversion system and a high-voltage formation system. The high-voltage formation system comprises multiple levels; each level comprises a Marx circuit and a LTD circuit. The Marx circuit is connected with a power source. A control signal which is input through the signal conversion system drives the Marx circuit and the LTD circuit. The LTD circuit is equivalent to a transformer. At the same level, the output end of the Marx circuit is connected with the primary side of the LTD circuit; and the secondary side of the LTD circuit at each level is connected in series and in sequence. By combining the respective advantages of the Marx circuit and the LTD circuit, relatively good balance can be achieved in the aspects of the voltage and current of the output pulse, and the application range of the compound mode solid pulse source is enabled to become wider. According to the pulse source, a relatively low power supply voltage can be adopted, and a relatively high output voltage peak value can be obtained after the voltage superposition of the Marx circuit and the LTD circuit. Through a flexible drive control mode, functions such as an output amplitude adjustment, a repeated frequency adjustment, output pulse width adjustment and output waveform adjustment also can be realized.

Problems solved by technology

The Marx circuit adopts the main idea of ​​"charging in parallel and discharging in series", which is suitable for generating high-voltage pulses. However, since the components of the Marx circuit are discharged in series, the total equivalent capacitance increases with the number of series series. increases and decreases inversely proportionally, so it is difficult to generate large pulse currents

The basic equivalent circuit of the LTD circuit is a 1:1 transformer. The system consists of multiple such circuits in series to generate high voltage. Since each stage of the circuit can connect many capacitors and switching devices in parallel, it can generate relatively large Pulse current, suitable for applications that require larger currents, but because its efficiency will decrease due to the loss of the magnetic core after each stage is connected in series, it is difficult to generate higher voltage pulses
