The working principle of a pulse power supply revolves around the generation of high-energy pulses at specific intervals. The core components of this system include an energy storage element, such as a capacitor, and a switching mechanism to release the stored energy in controlled bursts.
For this reason, STARTORUS FUSION adopts multi-level energy storage and switching topology. Considering the large number of PF power supplies and the extremely compact overall design, the H-bridge composed of dozens of IGBT high-current switches and energy storage components are highly integrated.
The simulation experiment has verified the correctness of the proposed superconducting energy storage pulse power supply topology and component selection, as well as the feasibility of the control method.
Pulse power, also known as "pulsed power", is the compression of electrical energy in both time and space with the goal of delivering fast, intense pulses of energy to a load.
The test results indicate that the device successfully achieves high-power pulse discharge, has sufficient capacity to ensure strong power and abundant electricity supply, demonstrating excellent performance of the high-power source.
This research has certain significance for improving the energy storage density of pulse pump power supplies for laser fusion. Further, when the processing technology is improved, it is expected to design more layers solenoid inductors in the future.
The high-power pulsed power supply is mainly composed of primary energy (for input), intermediate energy storage, conversion and release systems of energy (for output).
This integrated PPS comes with a complete system configuration, a miniature compact structure, a high rate of repetition, and high power, with energy storage density exceeding 1.2 MJ/m 3.
For the first mode, this proposed power circuit significantly enhances the amplitude of the voltage pulse, with the effect strengthens as the IGBT turn-on time increases.
A simulation model is established for a 30-stage XRAM pulse power supply with a railgun load using ICCOS. Each power module consists of five stages, resulting in a total energy storage capacity of 365 kJ for the system, with an emission efficiency of nearly 20%.
