Abstract :
A control method called resonant-tank control (RTC) is proposed for a parallel resonant converter operating above resonance. Using a simple linear combination of tank variables, it has potential for high-frequency DC-DC converter applications. RTC controls the tank in a near-time-optimal manner and is shown to have better dynamics than conventional frequency control. Experimental results that confirm the superior transient performance of the RTC method are provided. The principle of operation of the RTC can be extended to operation below resonance as well as to series resonant converter control
