A high-frequency DC-DC converter using a parallel resonant inverter operating above resonance is analyzed using a state-space approach and a constant current model. Closed-form solutions are obtained under steady-state conditions. The analysis shows that with some changes most equations are of the same form as those corresponding to operations below resonance. The analysis is also used to obtain the design curves and to provide a simple design procedure, which is illustrated by a design example. Experimental results obtained with a prototype MOSFET unit (using metal-oxide-semiconductor field-effect transistors as switches and operating above 90 kHz) are presented to support the theory.<>
