This device adopted the design idea of combining the frequency conversion and the voltage doubling, and included some technologies such as direct current chopping, series-resonant, optimizing of the voltage doubling and so on. The device has advantages of light weight, small volume and low cost, and can test the performance of the SPD on the scene conveniently and effectively to ensure safe and reliable operation of the SPD.
