摘要：The rapid development of electric power technology places a great demand on a safe and reliable power source with good performance. However, current power sources in market are mostly expensive, bulky in shape and heavy in weight. The three-phase AC power source is proposed in this paper based on the microcontroller KS22 (produced by NXP) and the direct digital synthesis (DDS) technology, which can realize high precision power generation with low cost stable performance and flexible operation. Through a friendly human-machine interface, the operator can adjust the frequency, phase and amplitude of the output signal conveniently, ensuring the output signal with high current, voltage, frequency accuracy and low waveform distortion at the same time.
