Analysis and Experimental Verification of Parallel Resonant Oscillator
<Abstract> This paper proposes a parallel resonant power oscillator that has the load-independent characteristic. The proposed oscillator is the first parallel-resonant power oscillator for high frequency operations. In addition, it achieves the constant output voltage and the soft switching against the load variations without any control. From the experimental results, we confirm the validity of the proposed oscillator. The implemented oscillator worked with 91.4 % power-conversion efficiency at 5.63 W and 937 Hz output. |
