    This digest proposes a control method for an integrated Triangular Current Mode (iTCM) operation of a single-phase AC/DC converter system. The proposed method achieves zero voltage switching (ZVS) of power semiconductor devices operated at high switching frequency, along with the desired input current total harmonic distortion. The proposed method does not depend on any zero-voltage detection or zero-current detection-based algorithms to achieve ZVS and thus is cost-effective and computationally less intensive. The efficacy of the proposed method is shown on a 2.4~kW experimental prototype operated at variable switching frequency over the fundamental cycle.
