Multi-objective optimisation of a bidirectional single-phase grid connected AC/DC converter (PFC) with two different modulation principles

Résumé

A design methodology is presented for a full-bridge Power Factor Corrector (PFC) converter with two control schemes: the well-known Continuous Current Mode (C.C.M) and Triangular Current Mode (T.C.M). The second one is an extension of the Discontinuous Current Mode (D.C.M). The converter is composed of one high frequency leg and one leg switching at the grid frequency and includes the EMC (common and differential mode) filter. This work highlights the impact of the modulation scheme on the design of passive components and on the overall losses. A pareto front in the efficiency (η) vs power density (ρ) domain is derived for both modulation schemes and for natural convection cooling. We show that, when EMC issues are considered, the T.C.M poses more constraints for partial load operation, superseding the full-load design. Finally, it is shown that for non-interleaved converters C.C.M modulation is better than T.C.M modulation, resulting in higher density converters.
