What makes Amp-Line Corp’s plasma power supply different from the power supplies on the market?

The difference between our plasma power supplies and the plasma power supplies on the market is that ours provides stable output voltage at different high frequencies within the operational frequency range of the HFHV transformer. This means that even as the plasma load changes, the generated plasma stays reliable for precise and repeatable plasma testing. Operators can focus on experimentation and measurement rather than searching for the new resonant frequencies. This makes our plasma power supply system a better and productive choice for high-accuracy DBD plasma applications.

The plasma power supplies on the market are made with LC resonant circuit (inductor-capacitor resonant circuits), where the capacitive load is usually the plasma load. Once the plasma is generated, the plasma load (C) value changes, which cause 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. This creates inconvenience in operation and unstable test results.

In contrast, our plasma power supply system maintains a stable high-voltage output across a wide frequency range (within the specified operational frequency range of the HFHV transformer) without the need for manual retuning. Our plasma power supply system is a combination of a wideband power amplifier and a high-frequency high-voltage step-up transformer. The wideband power amplifier drives the HFHV output transformer, and is made especially for accurate and stable testing on DBD plasma applications.
