Steady-state characterization of multi-phase, interleaved Dc-Dc converters for photovoltaic applications

A system-level, steady-state description of multiphase, interleaved boost converters is proposed for photovoltaic applications. The analyzed topology includes conduction losses in the coupled inductor, diodes and active switching devices. An interleaved switching scheme governed by ripple correlation control is deployed to maximize the power output of the photovoltaic source. The analytical derivations are validated against detailed numerical simulations, and their applicability over a wide range of ambient conditions is demonstrated.
