This paper proposes to use contactless power transfer (CPT) systems as electric plugs and outlets for household dc distribution system. In dc systems, there are higher risk of electric shock and longer arc discharge at disconnection compared with ac systems. The proposed system can connect and disconnect safely without electric shock and arc discharge because there is no contactor between primary side and secondary side. In this paper, an inductive contactless power transfer system was adopted. To reduce cost of system, a coreless transformer was selected. CPT circuit topologies and design of transformer coil form were considered. As suitable structure, a coaxial cylindrical transformer was proposed. Simulation results of 1 kW 400 kHz model and experimental results of developed 1 kW 400 kHz and 600 kHz prototypes were presented. The proposed system showed maximum efficiency over 93%.

The state of charge online estimation of EV/HEV lithium battery with high accuracy is very important, Since it can be used to prolong the battery lifetime and improve its performances. Traditional SOC estimation algorithms have show their drawbacks apparently, so the Adaptive Wavelet Neural Network(AWNN) based SOC estimation model is presented. By using adaptive algorithm to train the model, the accurate online SOC estimation is implemented. The simulation and experiment results are given and show that the proposed algorithm is an effective and feasible method to estimate the SOC of the lithium battery with fastest convergence speed and most high accuracy.

While hysteresis current control offers the benefits of a fast dynamic response and inherent overcurrent protection, its variable switching frequency and inherent two-level switching response make it unsuitable for many applications. This paper presents a new approach for three-level hysteresis control of a single phase grid-connected inverter that overcomes these limitations. The strategy adjusts the hysteresis band magnitude in response to variations in the inverter average output voltage, to achieve constant switching frequency using only one hysteresis comparator and without requiring DC offset compensation or current error zero-crossing measurement. The inverter average voltage is also used to estimate the phase of the incoming grid voltage, to create a current reference for the regulator at any required power factor. The result is a robust sensorless hysteresis current regulator suitable for three-level grid connected applications that operates with a constant switching frequency.

In high power applications, in which the discrete power switches are mounted on separate heatsinks, an overload of a semiconductor device leads to a local excessive thermal stress and eventually to a failure of the system. Despite of a control strategy that ensures the even distribution of losses in the normal operation, a local thermal overload can arise due to failures in the electronics, in the cooling system, due to an inappropriate positioning of the semiconductor device, etc. In this paper, a new fault tolerant control approach is introduced to deal with this matter. When detecting increased thermal stress of one IGBT module, the switching strategy is altered in order to reduce the load of that particular IGBT module and to redistribute the losses and consequently the heat from the affected group or valve to the other switches. Hence, the temperature of the stressed switch is kept under the critical limit and the thermal overload is reduced. In such way the reliability and the lifetime of the converter is maximized even in case of thermal failure. In the proposed novel modulation concept, the balancing of the neutral point potential of the 3L-NPC Inverter is also ensured without any additional hardware.

Mobile applications necessitate nowadays huge digital resources. Power management of digital circuits is based on dynamic strategies to preserve energy. DC/DC converters used to supply the digital core face stringent constraints with respect to load transients. Sliding-mode control is well suited to control buck converters that are subject to high dynamic load and line transients. Fixed frequency sliding-mode control has been experimented. Transient performances or silicon area are negatively affected. A new analog implementation of the sliding-mode control with switching frequency control is presented here. The proposed synchronization scheme does not degrade the intrinsic asynchronous transient performances and is not affected by a significant silicon area penalty. The proposed DC/DC converter is implemented in CMOS 130 nm. The switching frequency is kept constant thanks to the frequency regulation loop. The demonstrator achieves more than 80% efficiency from 3mW to 840mW.

Microbial Fuel Cells (MFCs) harness the metabolism of micro-organisms to generate electrical energy from organic matter. MFCs offer great promise for simultaneous wastewater treatment and green energy production. The association of a large number of individual MFCs offers very interesting perspectives for electrical energy generation. It can scale-up the low output voltage of an individual cell to enable output voltages to levels acceptable by commercially-available DC/DC converters and it permits to mutualize the electrical powers of each cell. The serial association of a large number of MFCs is a challenge itself for many reasons. Firstly the hydraulic couplings (when MFCs share the same substrate) witch cause leakage of electrical-charge careers between the connected reactors. Secondly the non-uniformities between generators which lead to a non-optimal energy recovery because the associated cells do not able to operate at Maximum Power Point (MPP). Non-uniformities can be compensated with electronic circuits to prevent voltage reversal or enable voltage equalizing. In this paper a balancing method is studied and adapted for energy harvesting from a stack of serially connected MFCs. The balancing circuit was simulated, realized and tested for energy harvesting. With balancing method the cell voltage of MFCs in a stack can be equalized and the performance of MFCs can be improved and it leads to an optimal energy recovery of the stack.

This paper presents two control techniques to minimize the circulating currents of the modular multilevel converter. The control techniques reduce the amplitude of each capacitor voltage ripple. Multicarrier level-shifted pulse-width-modulation is applied and the performance of interleaving and non-interleaving the carrier waveforms between the upper and the lower arms is reported. The total harmonic distortion of the output common voltage and rms value of the arms currents are benchmarked against the case when such techniques are not employed. The techniques have been verified by simulation using MATLAB/Simulink and PLECS Blockset software. Experimental results from a low power phase-leg prototype built with five sub-modules per arm are also provided.

This paper reports analytical modelling and analysis of the temperature dependence on the device characteristics of the AlGaN/GaN high electron mobility transistors (HEMTs). A physics-based model is proposed in this study in order to correctly predict the gate Schottky barrier height (ΦB), Fermi-level from conduction band energy (EC-EF), two-dimensional electron gas (2DEG) sheet density, gate threshold (Vth) and sub-threshold voltages (ID-VG), and drain current-voltage (ID-VD) characteristics under various high temperature (300K~500K) conditions. The analytical results are then verified by comparing with the laboratory measurement as well as the numerical results obtained from the Sentaurus TCAD simulation. The proposed model is found to be useful for power electronic device designers on the prediction of the AlGaN/GaN HEMT device performance under high temperature operation without the use of heavy numerical solving process that requires complicated customized computer coding.
