    Abstract: The present invention relates to a controlling method for multi-leg isolation DC/DC converter with wide input voltage scope, in which a transformer having at least three primary winding coils and one secondary winding coil is provided in a multi-leg DC/DC converter. Moreover, a converter controlling module is provided to treat the DC input voltage and the DC output voltage received from the multi-leg DC/DC converter with an over voltage determination, therefore the converter controlling module is able to output a proper driving signal to a plurality of power switch sets of the multi-leg DC/DC converter for making the power switch sets be operated at different ON/OFF states, so as to make the transformer has a specific coil turn ratio. By such way, the DC input voltage of the multi-leg DC/DC converter would be automatic modulated for facilitating the multi-leg DC/DC converter to provide a stable DC output voltage.

    Abstract: The present invention relates to a secondary side serial resonant full-bridge DC/DC converter, comprising: a transistor full-bridge unit, a transformer unit, a resonant unit, a rectifying unit, and an output unit. Particularly, in the present invention, a resonant inductor and a resonant capacitor of the resonant unit and a load resistor of the output unit constitute a serial resonant circuit having a serial resonant frequency; therefore, when the circuit frequency is operated on the serial resonant frequency, the resonant inductor impedance would be offset by the resonant capacitor impedance, such that the circuit is operated in the zero current switch (ZCS) region, and the output voltage variation can be controlled in ±0.2%. Moreover, through the serial resonant circuit, the issue about the resonant components hard to be designed due to their small characteristic impedance can simultaneously be improved.
