“…In (12) (13), the design parameters of the resonant converter for the energy loss have been mentioned, and the switching loss of the IGBTs is also described under multiple control modes. In addition, for the new energy application, a power supply device of LCC resonant converter is presented in (14), and for increasing the efficiency of the power system, lossless buffer capacitors are added in this circuit.…”

High-power converter applications are usually realized using the hard-switching technology under a low-switching frequency condition; moreover, the isolation transformer size must be larger. To reduce transformer size, the switching frequency must be increased; however, this increase directly results in the increase of switching loss. This paper proposes a high-voltage(HV) and high-power supply by using a thyristors-controlled rectifier and LCC series parallel resonant converter (LCC-SPRC). The introduced dc-dc converters are connected in parallel at the input side and in series at the output side, and soft-switching technology is applied to reduce the switching loss by using the frequency control mode. In addition, an equivalent mathematical model of LCC-SPRC with discontinuous current mode1 (DCM1) was analyzed in detail. For obtaining accurate parameters of LCC-SPRC, the Matlab/Simulink software was employed to calculate the system parameters, and provide the system with dynamic simulating curves. The simulation and experimental results verify that the LCC-SPRC design scheme of for supplying furnace power during the electron beam melting (EBM) is feasible in applications.

“…The FBSRC is another suitable topology for high‐power battery charger applications. However, designing a gain curve with a wide range of output voltage variations is not easy [19–27]. For high‐frequency operations at low output voltage conditions, parasitical components seriously affect converter performance.…”

This study presents a high-efficiency battery charger with cascode output design. The output voltage is cascode comprising two parts: one is fixed and the other is variable. High efficiency can be achieved under a wide range of output voltage variations. This topology can increase the utilisation of transformer duty cycle and reduce the power loss. The constant current and constant voltage charging schemes can be achieved by the proposed cascode configuration for battery charger applications. A 3.3 kW laboratory prototype is implemented and tested. The experimental results verify the feasibility of the proposed scheme.

“…This modular approach allows degraded operation with a faulty module [1] since a faulty module can be shunted without jeopardizing the operation of the converter. Moreover, using a soft-switched LCC resonant converter allows achieving a relatively high switching frequency with moderate losses [2], leading to reduced step-up transformers volume. This work focuses on the design of the high voltage stage of a modular 25 kV, 20 kHz resonant converter used to supplying a 200 kW RF tube.…”

This paper focuses on the study and the implementation of a 25kV / 200kW / 20kHz rectifier intended to supply radio frequency power amplifiers with a DC voltage in a precision range of 1000ppm. The topology is based on three LCC resonant modules, and the high voltage part uses three 100kW / 20kHz power transformers connected to 72 diode full-bridge rectifiers connected in series. The design of such transformers as well as the management of the voltage balancing between the rectifiers and between the modules constitute new challenges addressed in this paper. The key design points of the transformers are described. Then, a simulation based analysis presents the issues in balancing powers and voltages between the modules. All the presented results are validated by experimental measurements on a full scale system.
