An efficient and compact isolated DC‐DC converter is one of the most important components for electric vehicles (EV) and plug‐in hybrid EV (PHEVs) battery chargers. This chapter discusses efficiency oriented design considerations in detail on the operation mode analysis of the LLC converter including the characteristics of charging profiles. It draws the mode boundaries and distribution from the precise time domain model. The chapter identifies the operation modes featuring both‐side soft‐switching capability to design the operating trace of the charging process. It also discusses the design constraints for achieving soft‐switching with the load varying from zero up to the maximum. The chapter proposes and validates a charging trajectory design methodology through experiments on a prototype converting 390 V from the DC power source to the battery emulator in the range of 250‐450 V at 6.6 kW with a peak efficiency of 97.96 percent. It illustrates the proposed design procedure for the PHEV battery charger application.
