2 if the first and the second resonant converters belong to the same type and have the same design parameters the two resonant converters still may have different gains under the same frequency due to the discrepancies of the actual value of their elements such that the output currents are different and the difference between the two output currents is determined by the difference between the gains of the two resonant converters if the parallel connected first and second resonant converters belong to the same type but have different design parameters or the first and the second resonant converters belong to the different types e g the first resonant converter is a series resonant converter while the second resonant converter is a parallel resonant converter then the gains of the first and the second resonant converters under the same frequency may be different and the output currents are different the difference between the two output currents is determined by the difference between the gains of the first and the second resonant converters the input voltages of the first and the second resonant converters vin 1 and vin 2 are proportional to their gains since their outputs are parallel connected no matter what kind of aforementioned parallel connections is employed if an external disturbance causes io 1 io 2 gt m 2 m 1 at a specific moment under a dynamic status that is.
