Programmable Arbitrary Waveform Driving Power

摘要

This paper introduced programmable arbitrary waveform driving power. It is powerful piezolelectric actuator. Direct digital frequency synthesis (DDS) was used in arbitrary waveform generator. Floating power structure and push-pull structure were accepted in power amplify, impedance matching and harmonic distortion were ameliorated. With SOPC technology, spurious noise of DDS was improved. Arbitrary waveform required could be produced, including its frequency, phase and amplitude. Piezolelectric actuator was drove by 200W of waveform power.
