FAQ
1. What is the working principle of the SXCY Impulse Voltage Generator?
The impulse generator stores electrical energy in multiple impulse capacitors and releases the stored energy through controlled triggering and series discharge to produce a high-voltage impulse.
2. How many stages are available?
The SXCY Series can be configured with different numbers of stages according to the required output voltage. The product range shown includes configurations from 1–4 stages up to 18–24 stages.
3. What impulse energy can the system provide?
The listed configurations provide impulse energy ranging from approximately 7.31 kJ to 320 kJ, depending on the rated voltage, capacitance and number of stages.
4. What is the capacitor configuration?
The system uses impulse capacitors together with grading capacitors and wave-shaping components. Capacitor values are selected according to the required voltage and impulse waveform.
5. Why is low inductance important in an impulse generator?
Low inductance in the return circuit helps reduce unwanted circuit effects during the very rapid impulse discharge process, supporting more accurate and stable waveform generation.
