Abstract

The invention discloses a double-boosting high-voltage pulse power supply. The double-boosting high-voltage pulse power supply comprises a main circuit and a control circuit. In the main circuit, a 220V alternate current power source is sequentially connected with a rectifier circuit, a filter circuit, a Boost circuit, an inverter circuit, a pulse transformer, and a pulse rectifier circuit; and the pulse rectifier circuit outputs a high-voltage pulse finally. In the control circuit, a DSP (digital signal processor) system generates three paths of PWM (pulse width modulation) signals which are connected with three drive circuits through respective PWM amplification circuits; one path PWM signals is used for controlling an IGBT (insulated gate bipolar transistor) in the Boost circuit; and the other two paths of PWM signals are used for controlling an IGBT in the inverter circuit. Both the Boost circuit and the inverter circuit are provided with an IGBT protection circuit; the IGBT protection circuits can input fault signals to a DSP when the IGBTs have a fault; and the DSP can interrupt transmission of the PWM signals immediately, so that the IGBTs are kept in an off state, thereby protecting the overall system.

Description

technical field [0001] The invention relates to a high-voltage pulse power supply, in particular to a twice-boosted high-voltage pulse power supply. Background technique [0002] The pulse power has the characteristics that it adds the stored energy to the load in the form of electric energy with a single pulse or a short pulse with a repetition frequency. The reason why pulsed power technology is successfully applied in many fields is that it can obtain effects that other methods cannot or are difficult to achieve. [0003] After World War II, pulsed power technology continued to make progress driven by the needs of military applications, mainly in the development of pulsed power weapons and the development of simulation and diagnostic tools. In recent years, pulse power technology has been widely used in a series of military, energy, material, and biological fields such as radar transmitters, high-voltage pulse electric field sterilization, and electric pulse crushing of ...
