英文摘要：

A high-current, high-precision pulse type smart AC power system based on the LC series resonant principle is discussed. The power adopts DDS to generate specific frequency, by the H-bridge circuit to produce high-power square wave, and coil harmony with capacitance form a resonant circuit, and converted into power sinusoidal AC pulse. The instrument ieatures many merits such a high output power, high integration, and intelligent, portable security, has been applied to the actual product.
