Analysis of the static and dynamic characteristics of push-pull parallel resonant converters

The basic circuit of a push-pull parallel resonant converter with an input inductor is analyzed for the continuous conduction mode and the discontinuous conduction mode concerning the output-inductor current. It is found that the output voltage of this resonant converter is controlled by varying the switching frequency in the discontinuous conduction mode, while another power controller is required in the continuous conduction mode. The static and dynamic characteristics are examined analytically and experimenta1ly.
