The generators can be used both as medium frequency generators to generate symmetric AC current and as bipolar pulse generators to generate asymmetrical square pulses. With a special power ratio controller the target lifetime for dual magnetrons can be exactly symmetrized. Furthermore, two different target materials can also be controlled with asymmetrical pulse power. The power ratio controller automatically sets the pulse times via pulse width modulation (PWM). The units work with a fixed frequency of 20 kHz. The generators have an automatic arc suppression. The parameters for trip level and break times are automatically adjusted to the chosen process. Programming by the user is not necessary. For an automatic synchronization, multiple generators can be connected via control cables. In this case, the pulse generators automatically switch to external synchronization.
