The evolution of new battery technologies and unique system requirements has created a demand for intelligent power electronic battery-charger solutions. This paper will present a method showing how to develop a programmable solution that supports multiple topologies and hardware designs that can be used to safely and reliability charge existing and future battery chemistries, in addition to super-capacitor energy storage needs. Common and popular battery-charger topologies, such as Buck, Flyback, SEPIC and Cuk', will be used as examples. Using this method, accurate constant voltage and charge current can be achieved with all topologies via a common firmware platform and a highly integrated hybrid PWM controller.

This paper proposes a method for the power factor coordination of distributed generators by a multi-agent approach. The proposed multi-agent system consists of two types of agents: a single feeder agent (F_AG), and several bus agents (B_AGs). A F_AG plays the important role of deciding the power factors of all distributed generators by repeatedly executing the load flow calculations. The voltage control strategies of the system are implemented as the class definition in Java. To verify the performance, the proposed method was applied to a model system. The simulation results showed that the system is able to control very violent fluctuation of demand and photovoltaics (PVs).

In this paper, an advanced fast-charging strategy for lithium polymer (Li-Po) battery is proposed, in which a two-stage charging current profile is employed. First, the constant charging current is used and when the battery voltage reaches a specified value, the charging current is reduced according to the root square of time. With this strategy, the charging time is shortened and the discharging energy is increased. The experimental results show that it is capable of charging the battery up to 84% capacity in 28 minutes compared with the constant current and constant voltage charging and pulse current charging methods.

If the structure of wind turbine generator's drive train model is too simplified, it may not reflect the subsynchronous oscillation (SSO) mode. The types and sizes of wind turbine generator (WTG) are various. Therefore, the parameters of drive train model vary widely. There is an urgent need to study the effects of drive train model's structures and parameters on SSO. In this paper, mass-spring-damping shaft models of WTG are presented. Eigenvalue analysis is used to study the effects of drive train model on SSO. The results show that, if two-mass model is adopted, only the low-frequency oscillation (LFO) exists. If three-mass model is adopted, there will be the LFO and SSO. In inertial constants, the inertia of hub (Hh) has the greatest effect on SSO. With the increasing of Hh, the frequency and damping of SSO decrease. In spring constants, the spring constant between hub and generator (Khg) has the greatest effect on SSO. With the increasing of Khg, the frequency of SSO increases, yet the damping decreases. In damping constants, the damping constant of hub (Dh) has the greatest effect on SSO. With the increasing of Dh, the damping of SSO increases. Damping constants almost have no effect on the frequency of SSO.

This paper proposes simple power line communication (PLC) method among DC-DC converters in DC distribution network system. In this method, current ripples in the converters' inputs are used as signal carrier whose frequency is modified as a function of information data. The modulator is easily realized by just adding a transistor and a resister to conventional PWM control circuit. Demodulator is also realized by simple analog circuit. With proposed method, the converters are capable of bidirectional data transmissions among all converters in the system. Circuit simulation results show the effectiveness of proposed method.

As a conventional high-voltage reactive power compensation device, high-voltage thyristor switched capacitor (TSC) reactive power compensation device is widely used in high-voltage areas. However, when the thyristor is turned on completely, the valve terminal voltage is zero, and trigger circuit can not taken energy from the damping circuit to trigger thyristors. In order to solve the problem, the self-power supply optoelectronics trigger circuit has been a hot research. A set of device based on self-power supply photoelectric trigger 10 kv High-voltage TSC is proposed in this paper. It can delay a certain angle to achieve self-power supplying of the thyristor trigger circuit. It will result in a surge current due to the impact of voltage jumping when firing angle delay exists, which causes the trigger pulse disorder further. Therefore, in order to restrain the surge current, the reactor must be configured properly in actual. In this paper, the relationships between TSC trigger pulse delay angle and reactor and the harmonic content are analyzed according to the theory and simulation results.

Field experiences have demonstrated that semiconductor devices are vulnerable to failures. This paper investigates the fault analysis regarding conventional parallel inverter systems. The stage analysis for the parallel inverter system in case of IGBT short-circuit is analyzed firstly. Then, the current impacting on the inverter system due to the IGBT short-circuit failure of one inverter is discussed. The corresponding peak fault current and fault isolation time are explored. The mathematical expressions for these two issues are derived, which is helpful for the redundancy design of the system. Finally, the experimental results are provided to verify the theoretical analysis.

In this paper, a simple fault-tolerance control method for a dual-PMSM speed drive system is investigated. The proposed method does not require any additional hardware. By suitably changing the switching states, a fault-tolerant control dual-PMSM drive system can be achieved. The fault-tolerant system can be applied for high-reliability applications such as, electric vehicles and other electric propulsion systems. The proposed system is implemented by using TMS320F2808 digital signal processors. Several experimental results show the validity and feasibility of the proposed method.

This paper proposes a direct space vector modulation of a three-phase AC to single-phase AC isolated matrix converter. In order to introduce the direct space vector modulation, this paper discusses the relationship between high frequency square wave of the single-phase side and an equivalent circuit of the matrix converter. In addition, this paper introduces both of the buck type and boost type of three-phase AC to single-phase AC isolated matrix converter. In the buck type matrix converter, switching number increases due to the changing of zero vectors when the input current reference vector moves to the next sector. This paper discusses optimized switching pattern for the buck type matrix converter in order to reduce the switching number. The proposed space vector modulation method is confirmed by the simulation results.
