In this paper, a current-sharing method for an interleaved high-frequency LLC converter with partial energy processing is presented. A small transformer and an auxiliary low-power dc-dc converter are added in each phase, and the current sharing between phases is achieved by controlling the duty cycle of the auxiliary converter. Only partial energy is processed by the auxiliary converter; hence, the power losses of the added auxiliary converters are minimized, and the overall high efficiency is maintained. By transforming the current sharing of the resonant converter into pulsewidth modulation control of a dc-dc converter, the proposed method is simple to implement and easy to extend to multiple phases. The frequency of the auxiliary converter is independent of the main LLC, so the LLC can operate at a fixed switching frequency and duty cycle, and it is suitable for high-frequency applications. The operating principle, design considerations, and the control schemes are presented, and a 1-MHz two-phase interleaved LLC prototype was built to verify the theoretical analysis.
