What is a pulsed current source?
This paper presents a simple yet effective design for a pulsed current source, incorporating a solid-state Marx pulsed adder as the primary power source and an inductor for energy storage. In the pulsed current source, a Marx pulsed adder produces high voltage to charge the inductor.
How pulsed constant current source can be used for closed-loop current control?
As the present of pulsed constant current source have problems of low amplitude and repetition frequency, we design a pulsed constant current source adopting integral feedback to get closed-loop current control, build the mathematical model and verify the function of the circuit by Pspice.
How many units are in a pulsed current source?
The module of the pulsed current source that can generate pulses of voltage 20 kV and current 10 A contains 24 units, and each energy storage capacitor in the unit should be charged to ~ V. Figure 1.
How is pulsed current provided?
The pulsed current was provided using the proposed IGBT-based power supply system operating in the burst mode. One important advantage of this system was a small amount of the stored energy transferred in load upon the breakdown in the accelerating gap.
How can a pulsed current source be controlled?
Composed of solid-state devices, it can be controlled by low-voltage logic devices through isolated drivers. Referring to the formulas given, it is easy to modulate a variety of current pulses with different parameters by changing the switching time. There are two cascade methods for pulsed current sources: overall cascade and packet cascade.
What happens after a pulsed current source is initialized?
When working in repeated pulse mode, the pulsed current source has three circular operating processes after initialization: load current chopping synchronized with capacitance charging, inductance charging and load discharging. The initialization is similar to the single pulse mode.
