Abstract

A current-fed series resonant inverter suitable for high-frequency, high-power applications is introduced and analyzed. Steady-state characteristics of the inverter are obtained using a normalized state-space model. The switches´ stresses and the resonant components´ ratings are obtained for various controlling parameters, such as the switching-to-resonant frequency ratio and the Q-factor of the resonant tank circuit. These curves are used in designing the inverter for different values of input current, output voltage, power, and frequency
