Tired of Retuning Your Standard Plasma Power Supply? Here’s a Better Solution
For many researchers, plasma experiments come with a familiar frustration: constant tuning of the output frequency to match the new resonant frequency on standard plasma power supplies that use LC resonant circuits.
The plasma power supplies on the market are made with LC resonant circuits (inductor-capacitor circuits), where the capacitive load is usually the plasma load. Once the plasma is generated, the plasma load (C) value changes, which causes the resonant frequency of the LC circuit to change. As a result, the output voltage (high voltage) will drop accordingly unless you manually tune the output frequency to match the new resonant frequency. Even the slightest change in the load requires manual retuning of the output frequency—a slow, tedious process that interrupts experiments and risks inconsistent results.
At Amp-Line, we take a different approach. Our plasma power supply systems are a combination of a wideband power amplifier and a customizable HFHV step-up transformer. This setup delivers the stable high-voltage output across the specified operational frequency range of the HFHV transformer without the need for manual retuning, giving researchers the freedom to focus on experiments rather than equipment adjustments.
Sample Scenario:
A customer provided the following requirements for their tissue sample testing:
Voltage: Up to ±2 kV (4 kV peak-to-peak)
Peak Current: 10 A
Peak Power: 20 kW
Frequency: 50 kHz to 100 kHz
To meet these needs, we designed a custom HVHF transformer with the following specifications:
Primary Voltage: 28 V rms.
Secondary Voltage: 1415 V rms. (4000 V peak to peak)
Frequency Range: 50K Hz – 100K Hz
Output Power: 4000 watts
And paired with a wideband power amplifier with the following specifications:
Input Signal: 0-2 V rms.
Output Voltage: 0 - 28 V rms. adjustable
Max. Output Current: 50 A rms.
Frequency response: 5 Hz – 600K Hz
Output Power: 1400 watts
In this plasma power supply system (the wideband power amplifier driving the HVHF step-up transformer), a stable output voltage of 1415 V rms. (4000 V peak-to-peak) is delivered across the entire operational frequency range of 50 kHz to 100 kHz. This allows for consistent, accurate, and repeatable plasma testing, critical for applications such as tissue sample research —saving time, reducing error, and improving consistency.
At Amp-Line, every transformer and power amplifier we design is treated with care, precision, and innovation. Whether you are conducting biological tissue research, DBD plasma experiments, or other specialized applications, we work closely with you to identify the optimal configuration for your needs.
