Resonant-tank control of parallel resonant converter

A control method, named resonant-tank control (RTC), is proposed for a parallel resonant power converter (PRC) operating above resonance. Using a simple linear combination of tank variables, it has potential for high-frequency DC-DC power converter applications. RTC controls the tank in a near-time-optimal manner and is shown to have better dynamics compared to conventional frequency control. Experimental results to confirm the superior transient performance of the RTC method are presented.<<ETX>>
