Detailed analysis and design strategy method have been done to show the effect of replacing the two filters without magnetic coupling usually used for reducing the current ripple in the interleaved regulator by an interphase reactor. The main attention is focused on the synthesis, analysis and simulation of the two-phase parallel connection of interleaved regulator with directly coupled filters known as an interphase reactor. A comparison of the two-phase connection with uncoupled smoothing filters or with magnetically coupled filters is done. Actual criteria for comparison may be carried out from dynamic behavior and performance, technical parameters and investment perspectives. Technical parameters are considered to be: Distribution of currents into phases and harmonic content. Investment costs depend on demands to the material needed for designing the filters. For an interphase reactor with inversely coupled damping filters, phase current ripple can be reduced if operating points and coupling coefficients are carefully chosen. On the other hand, an interphase reactor with directly coupled damping filters has the advantage of low sensitivity to input variation at high frequencies [2]. Generally, the use of interphase reactor with directly or indirectly coupled damping filters helps in equal distributing of currents into phases without using control methods and it helps in removing the harmonic content (the amount of the ripple in the load current and voltage) as compared to that with uncoupled damping filters without the need for special filters. Computer simulations in Simplorer and Matlab/Simulink have been done and software prototypes have been prepared to verify the results.

INTRODUCTION A stepping up interleaved regulator with smoothing filters is commonly used in applications such as powering microprocessors. They are ideal for converting a 5V-system to the 2V or so, at up to 20A that processors require. It is also widely used for traction motor control in electric automobiles, trolley cars, marine hoists, and mine haulers [2].
