This phenomenon is often seen in previous designs. Therefore, the resistor R1 has another function that it acts as a damper for the Lp−C1 resonant circuit. Then, a compromise between the two opposing operations should be considered. For a series LCR resonant circuit, the damping ratio can ...
2 Derivation of the proposed topology The proposed circuit has been derived from the conventional three-level T-type vienna rectifier topology, as shown in Fig.2. The structure of conventional T-type vienna converter [47,48] is shown in Fig.2a. It consists of a single leg of two back-to...
Vitzro EM Co is based in Seoul, South Korea, and is a manufacturer of electric power systems and equipment that was established in 1989 as a subsidiary of the Vitzro Group. The company offers vacuum circuit breakers (VCBs) that utilize vacuum pressure to interrupt electric currents, and gas-...

The AC equivalent circuit of a traditional LLC converter is shown in Figure 5, where the mutual inductance M is much larger than the secondary-side leakage inductance Lr2. The transfer power of the LLC converter can be approximately expressed as 𝑆𝐿𝐿𝐶=𝑣2(𝑣1−𝑣2)𝑗𝑤...
(c) According to the theoretical derivation scheme, a test prototype is designed to verify the correctness of the proposed theory. The rest of this paper is organized as follows. In the Section 2, the proposed circuit model is introduced systematically, including the dual-power equivalent model ...
