Abstract :
A parallel resonant convertor (PRC) operating in the continuous conduction mode (CCM) is analyzed, using a high loaded quality factor QL assumption (i.e., QL>2.5) and Fourier series techniques. Simple analytical expressions for performance characteristics are derived under steady-state conditions for use in designing and understanding the behavior of the PRC. Three Class-D voltage-driven rectifiers are analyzed, taking into account the diode threshold voltage and the diode forward resistance. Experimental results measured for a 50-W convertor above the resonance at different load resistances and input voltages show excellent agreement with the theoretical performance predicted by the equations
