In order to meet the requirements of electrolytic copper-foil, a 6.5V/50kA power supply system composed of ten power modules is developed. The power module is composed of two-leg PWM rectifier and dc/dc converter, and dc/dc converter adopts two full-wave rectifiers in parallel to enhance the output ability. In order to meet the process requirements of electrolytic copper-foil, a virtual impedance based current-sharing control method with load current full feedforward is proposed for n-parallel dc/dc converters. The virtual impedance is used to adjust the current-sharing impedance without changing the equivalent output impedance of converter. It can effectively improve the output performance and eliminate the current-sharing errors. Finally, simulation and industrial application results have verified the structure and control method.

In order to solve the problem of poor re-producibility and large particles in pulse bias arc ion plating (AIP), this paper proposes an incremental fuzzy control scheme based on the extended state observer(ESO) for DC/DC converter. According to researches about equivalent load model of pulse bias AIP in the vacuum environment, the relationship between the influence factors on load and output performance is discussed. Then, based on the small signal model of DC/DC converter, a new 3-order mode-compensation ESO is built to decrease the observing error. In addition, the method of phase plane for designing fuzzy control rule is presented to optimize the rule, and the stability of designing fuzzy control system is analyzed by the Lyapunov theory. The simulation and experimental results have demonstrated that the tracking performance and robustness of pulse bias power supply with the proposed scheme are significantly improved.

It is of advantage to harvest and dispatch power within a minimal number of conversion steps. This paper proposes a single-stage multi-input multi-output converter (MIMOC), which can be used for interfacing diverse energy sources and loads in future smart homes with dc power distribution architectures. The proposed MIMOC offers compact structure, centralized control, galvanic isolation, and wide voltage conversion ratio with precise voltage regulation. The operation principle of the proposed MIMOC is analyzed. A specific switching pattern is proposed, and a multivariable PI based control scheme is presented that enables budgeting the input powers coming from different sources in addition to regulating several output voltages. Both switch and average models are provided to validate the operation of the proposed MIMOC.

There is discontinuous input current or output current in most of the isolated DC-DC converter. If continuous current is required, generally we need to add additional bulky filter, which will reduce the system's power density. In this paper, the method of adding a built-in filter to the isolated converter to achieve a continuous input current was employed. The built-in filter is composed of transformer leakage inductor and cross-coupled capacitor. Two kinds of push-pull converters with built-in filter which are derived from the voltage-type push-pull converter are proposed in this paper. The working rules and the results of PSIM simulation are given. A prototype was built in our lab to verify the synthesizing theory. The experimental results have verified the theoretical analysis.

This study presents a novel topology named high voltage-gain boost DC-DC converter with tapped-inductor. The proposed topology provides a high voltage-gain and low input current ripple which are suitable for alternative power sources such as PV and fuel-cell applications. The interleaved control mode can be used to reduce input and output filtering. Moreover, the voltage stress on MOSFETs are clamped, resulting of low on-resistance(RDS(ON)) MOSFET usage to improve efficiency. Addition to providing circuit operation and analysis with symmetric control and interleaved control modes, a simulation and laboratory prototype of the proposed topology was built and inspected under 15-28 V input, 400 V/250 W output and 100 kHz switching frequency. The results showed that the proposed circuit achieved low voltage spikes on MOSFETs. Low RDS(ON) MOSFETs were used to improved efficiency. For interleaved control mode, the input current ripple and output voltage ripple were low, requiring smaller input and output filtering.

A novel multilevel cascaded bridgeless rectifier typology is proposed by this paper with the aim of eliminating the bulky and complex line frequency transformer from the front end of the traditional multilevel converters. The module of the rectifier is composed of the bridgeless rectifier. Through applying suitable control strategy, the input current can be programmed to be sinusoidal and nearly in phase with the input voltage; in addition, the output dc voltage of each module can be controlled in balance. The performance of the novel multilevel cascaded bridgeless rectifier is investigated through theoretical analysis and simulation. The validity and effectiveness of the proposed rectifier is verified through the experiments in a small scale test platform.

In this paper, interleaved LLC half-bridge resonant converters are designed and implemented. In order to increase output power, two LLC resonant converters are parallel-connected. The gate driver signals of two LLC converters are interleaved by 90˚ to reduce output-current ripple. Besides, switch losses on power devices can be reduced by zero voltage switching(ZVS) and zero current switching (ZCS) on output diodes. The characteristics of the proposed topology are discussed, and the operation principles and control circuit design are also addressed in this paper. Finally, interleaved LLC half-bridge resonant converters with input 380~420 V and output 24 V/20 A is implemented to verify the theoretical feasibility.

A novel topology of half bridge three-level full bridge bidirectional DC-DC converter is proposed. The configuration and operational principles of the novel converters with the dual-phase-shifting control were analyzed. The ZVS soft- switching range of the left three-level half bridge and the right H-bridge under different voltage conversion ratio were discussed. In order to improve the whole system efficiency, Based on the mathematical models of transmission power and backflow power, the equation describing the minimum backflow power under the given transmission power was formulated. The dual-phase-shifting optimized control strategy with the minimum backflow power for different given transmission power under ZVS soft-switching conditions were proposed. At last, the experimental results were presented to validate the theoretical analysis.
