Parametric High-Voltage Pulse Experimental Power Supply
Parametric High-Voltage Pulse Experimental Power Supply
Product Detail
The ACS Material Parametric High-Voltage Pulse Experimental Power Supply is a fully adjustable pulse source for discharge research. Pulse amplitude, pulse width, rising and falling times, frequency, period, duty ratio, waveform shape (square or triangular), load matching, and the number of output pulses can all be set to the user's requirements. This makes it possible to study gas-discharge characteristics comprehensively and to capture discharge-initiation moments accurately. Two models are available: the EPPHVP20 (0–20 kV) and the EPPHVP15 (0–15 kV).
Key features
- Adjustable parameters — all parameters of the high-voltage output pulses, especially the rising and falling times, can be set and adjusted, for a comprehensive and systematic approach to discharge-related research.
- Load matching — the pulse source adapts to different loads, with output waveform characteristics selectable and adjustable based on the load, so the high-voltage pulse waveform meets user requirements.
- Controlled electromagnetic interference — the output high-voltage waveform is controllable, significantly reducing the EMI caused by fast nanosecond pulses and minimizing the impact on other test equipment.
How pulse parameters shape the discharge
The rising and falling edges of high-voltage pulses have the greatest impact on the timing of gas discharge. The pulse width significantly affects the distribution and uniformity of the discharge, while the pulse frequency may influence the stability and efficiency of the discharge. Each pulse parameter affects discharge characteristics differently across application fields, so a parametric source with fully adjustable waveform parameters is a powerful tool for systematic discharge research.
