A HIGH GAIN INPUT-PARALLEL OUTPUT-SERIES DC/DC CONVERTER WITH DUALCOUPLED-INDUCTORS.

This paper presents a very distinctive boost device with twin coupled-inductors and a voltage variety module. On the one hand, the primary windings of two coupled-inductors unit of measurement connected in parallel to share the input current and deate this ripple at the input. On the other hand, the projected device inherits the deserves of interleaved series-connected output capacitors for prime voltage gain, low output voltage ripple and low switch voltage stress. Moreover, the secondary sides of two coupled-inductors unit of measurement connected asynchronous to a regenerative device by a diode for extending the voltage gain and leveling the primary-parallel currents. In addition, the active switches unit of measurement turned on at zero-current and conjointly the reverse recovery disadvantage of diodes is relieved by low cost leak inductances of the coupled inductors. Besides, the energy of leak inductances is recycled. [ABSTRACT FROM AUTHOR]
