N2 - Electromagnetically Induced Acoustic Emission (EMAE) technology is a new type of Nondestructive Test (NDT) techniques, which does nondestructive detection with the effect of dynamic electromagnetic loading to generate a stress field stimulating stress waves from the defects. In order to satisfy the requirement of EMAE testing, such as high power output, pulse counts adjusting and the frequency of the output in wide range, a new power supply based on Direct Digital Synthesis (DDS) is designed. The power supply includes signal generating, power amplifying and series resonating, which the control circuit is the core part. Experiments' results show that the system can satisfy the requirement of EMAE testing with the merits of outstanding stability and flexible parameter adjustment.
