Advanced Energy’s high-voltage power amplifiers employ unique and proprietary circuitry to produce a closed-loop amplifier system that features exceptional DC stability and excellent wideband performance characteristics. Featuring all-solid-state construction, Advanced Energy’s amplifiers are fully protected against arc-over and operation into short circuits. Advanced Energy power amplifiers employ a unique four-quadrant class AB high-voltage output stage which is constructed using MOS power transistor devices in a proprietary multidevice cascode connection. This cascode connection provides tight voltage and power-sharing across all devices in the cascode array to yield exceptional MTBF reliability performance.

Theory of operation
As the closed-loop amplifier system’s stability depends on the feedback voltage divider stability over time, temperature, and humidity, Trek employs an advanced thin film resistance technology in its feedback dividers. The signal from the feedback divider, being a precision-divided representation of the amplifier output signal, is used to provide a low-level voltage monitor signal and to complete the feedback loop by comparing the divider output against the amplifier input signal in a high-gain integrating stage (A). The output of the integrating stage is used to drive optical couplers connected to the output stage cascode connected MOS device arrays, thus closing the feedback loop. To generate the high-voltage required by the output stages, high-voltage, high-frequency switching type power supplies are typically used.
