Hybrid Control of Self-Oscillating Resonant Converters

We describe parallel and series resonant converters (PRC and SRC) via a unified set of input-dependent coordinates whose dynamics are intrinsically hybrid. We then propose hybrid feedback showing a self-oscillating behavior whose amplitude and frequency can be adjusted by a reference input ranging from zero to $\pi $ . For any reference value in that range, we give a Lyapunov function certifying the existence of a unique nontrivial hybrid limit cycle whose basin of attraction is global except for the origin. Our results are confirmed by experimental results on an SRC prototype.

Automated summary

This article describes parallel and series resonant converters and proposes a hybrid feedback system with self-oscillating behavior. The amplitude and frequency of the system can be adjusted by a reference input. Experimental results confirm the effectiveness of this method.
