摘要
The switching cell consisted of transistor and it's driver circuit are the most critical components in a high frequency power converter. Switching of high frequency current, despite of application of soft switching techniques, causes serious stress to the switching device. The parasitic components of both driver and power circuit can further disrupt the commutation process and contribute to the significant FFT spectra deterioration. Thus, a resonant filtering circuit was proposed, which significantly reduced voltage oscillations and improved operation of 4 MHz RF generator. Significant improvement was proven for both 50 Omega load and mismatch conditions.
