“…A new loss-limited dc-dc converter topology employing one resonant soft-switching pole and one phase-shifted hard-switching pole has been introduced recently for high-power isolated dc-dc power conversion [1]. Comparative analysis of this topology with alternate dc-dc converter topologies has demonstrated the viability of the new topology [4].…”

“…The loss-limited dc-dc converter topology uses low-leakage coaxial-wound transformers along with a novel primary commutation scheme that limits the switching loss, a split secondary that permits the use of lower voltage diodes, and an energy recovery clamp for diode recovery [1]. The converter topology is shown in Fig.…”

“…The efficiency of the prototype power converter under various modes of operation was measured to be over 96% confirming the expectations. Details of the power circuit design and steady-state operating conditions have been presented in [1]. A computer-simulation-based comparative evaluation of the proposed converter with other approaches for realizing such isolated high-power system indicates that the proposed approach provides superior performance [4] from a thermal point of view.…”

“…Recently, a loss-limited switching dc-dc converter employing one resonant soft-switching pole and one phase-shifted hard-switching pole was demonstrated to be an effective means of realizing the same [1]. Production units of this converter that provide 750 V at 180 A (135 kW) have been used to feed 18 isolated dc buses for a cascaded-multilevel-inverter-based motor drive system [2].…”

Abstract-Full-bridge dc-dc converters with one soft-switched leg and one hard-switched leg have recently been introduced as an attractive approach for realizing high-frequency power conversion at power levels greater than 100 kW. This paper presents a new variable-frequency multimodal control strategy for these converters for obtaining optimal operating characteristics. The controller extends the soft-switching operating region of the converter while lowering magnetic component core loss. Steady-state and dynamic analyses of the converter operation in the various modes are developed. Simulation and experimental results verifying the operation of the converter are presented.

SUMMARYThis paper proposes a new configuration of UPQC (Unified Power Quality Conditioner) that consists of the DC/DC converter and the super-capacitors for compensating the voltage interruption. The proposed UPQC can compensate the reactive power, harmonic current, voltage sag and swell, voltage unbalance, and the voltage interruption. The performance of proposed system was analyzed through simulations with PSCAD/EMTDC software, and the realization of proposed system was verified through experimental works with a prototype. The proposed system can improve the power quality at the common connection point of the non-linear load and the sensitive load.
