High-frequency power packs with sinusoidal output are often required in different fields of scientific investigation. The conventional designs of such sources are associated with some critical and complex problems. The authors devised a simple circuit using a solid-state power-transistor switching system actuating a pulse transformer as its load where the equivalent inductance and distributed winding capacitance play the critical role of wave generation. The sinusoidal pattern is generated from 500kHz and above. The value of distributed capacitance determines the required region of high-frequency bandwidth at the secondary output. The portability, economy and simplicity make this superior to other conventional devices.
