The Bipolar Pulse Generator GXB 50 generates a square-wave
AC voltage for plasma excitation between two cathodes. A 5 kW-DC power supply is already integrated, so that no external DC power supply is necessary. The generator works with a fixed frequency of 22.5 kHz. Pulse-on time and pulse-off time are automatically controlled and not preset as determined parameters. A special current ratio controller calculates the power of both half-waves and regulates them on the basis of Pulse Width Modulation (PWM) in a pre-defined proportion. The Bipolar Pulse Generator is equipped with automatic arc suppression. The parameters for trip level and break times are automatically adjusted to the specific processes.
