【Abstract】 This paper introduces a high-power sine wave signal generator based on the principle of resonance. By using the inverter switch circuit, the generator can produce signals of square waves with variable amplitude and frequency. The generator can produce sine waves through the LC resonance loop. With advantages such as high output power, a wide range of adjustable frequency, a small volume and light weight, the generator has been put in successful use in the measurement instruments for the AC magnetic characteristics of soft magnetic materials.更多还原
