Abstract

Abstract

The voltage droop of high-voltage pulses is required to be as low as possible in many industrial applications including particle accelerators. The commonly used method of reducing the droop is to increase the capacitance of the energy storage capacitors at the price of lower energy efficiency, bigger size, and higher power of the system. Another method is to insert some special stages to compensate for the voltage droop. When a resonant inductor and a switch in series are connected in parallel with the capacitor in a common stage in solid-state Marx generators (SSMGs), a compensation stage is obtained. In this paper, four compensation stages based on resonant circuit have been inserted into a 16-stage SSMG to compensate for the voltage droop with different loads and different pulse widths. The nearly linear part of the sinusoidal voltage is precisely added to the load during discharge as compensation and the rectangular pulsed voltage with little droop can be realized. Different numbers of compensation stages can compensate the droop to different levels, which means the compensation effect is also adjustable. Moreover, these compensation stages can also operate as common stages in Marx generators as long as the resonant circuits are open. Since the capacitors in resonant compensation stages are also charged in parallel with capacitors in common stages, no auxiliary power supply is required. Experimental results show that the droop of 2.5 kV and 10.5 kV pulses can be ideally compensated over 400 Ω and 5 kΩ resistive loads, respectively. The pulse widths should be shorter than the length of the nearly linear part of sinusoidal voltage for better compensation effect.
