    This paper proposes a new family of zero-voltage-switching multi-resonant three-level converters (ZVS-MR-TLCs), which is derived by introducing a LCC multi-resonant network to the basic three-level converters. The unique arrangement of a multi-resonant network results in absorption of all major parasitic components in the resonant circuit, including switch output capacitor, diode junction capacito...

    A novel ZVZCS three-level PWM phase-shift controlled converter with regenerative passive snubber in the secondary is considered. The voltage stress on the rectifier diodes is reduced to n(V/sub in//2) (n is the transformer turns ratio) by using a few additional elements in the primary: two diodes, a small inductor and a small transformer winding. The conditions assuring ZVS of the leading leg and ... View full abstract»

    For high-voltage charging applications, this paper introduces a variable-frequency zero-voltage-switching three-level LCC resonant converter, which is able to utilize the parasitic components of the high-turns-ratio transformer. By applying the three-level structure in the primary side, low-voltage MOSFETs can be used to minimize the conduction loss. Therefore, the switching frequency can be incre... View full abstract»

  • Multiple frequency modeling of high frequency resonant inverter system

    Multiple-frequency modeling (MFM) offers a general small signal modeling methodology for resonant type converters. A DC/AC resonant inverter is decomposed into two pure DC sub-circuits for each harmonics, the excitations of which are orthogonal. However, such decomposition makes the definitions of active power P, reactive power Q, apparent power S and instantaneous power p difficult, while these c... View full abstract»

    In this paper, a new digital deadbeat controller is designed, implemented, and applied to a three-phase series-parallel line-interactive uninterruptible power supply (UPS). This topology consists of a parallel and a series converter. In this topology, most of the power is supplied directly from the AC line to the load. Therefore, the overall efficiency is higher than that of the on-line UPS. The c... View full abstract»

    This paper proposes the concept of integrated ZVT auxiliary commutation circuits applied to systems with power conversion multi-stages. With this concept, it is possible to reduce the number of additional elements as well as to minimize the circulating reactive energy. A new integrated ZVT auxiliary commutation circuit is applied to a double-conversion UPS to demonstrate the functionality of this ... View full abstract»

    A three-phase PWM rectifier and a three-phase PWM inverter are coupled via two four-quadrant full-bridge converter cells and a high-frequency isolation transformer. By employing a third transformer winding and further full-bridge cell battery energy storage is incorporated into the power transfer between rectifier and inverter resulting in a three-port UPS concept. The phase shift control of the p... View full abstract»
