  • This paper presents a multi-module parallel single-phase battery energy storage system (BESS). The single module BESS to be paralleled consists of only a full-bridge converter. When the utility is in normal condition, the BESS serves as a power conditioner as well as an active power filter. It can be arranged to charge the battery bank or to share daily peak load. In any case, the current supplied by the utility can be maintained sinusoidal and almost in phase with voltage. When the utility power failure happens, the BESS functions as an inverter to supply uninterruptible power to the load. Withmore » the good current sharing feature possessed by this BESS, a central power distribution control scheme with smooth current transfer characteristic is proposed to control the parallel operation of the multimodule BESS. The current sharing of each BESS module can be programmed according to its rating and the load condition. Designs of the power circuit, and the central power distribution control scheme are described in detail in this paper. The effectiveness and performance of the proposed parallel BESS are demonstrated by some experimental results.« less
  • In plasmas with strong field aligned currents, the most unstable mode is not always at parallel propagation, but may be at intermediate and very oblique angles. 2D particle simulations are performed in order to examine the interaction between the plasma waves at various angles and the electron and ion distributions in low {beta} collisionless plasmas with strong electron drifts. The parallel Buneman instability is known to arise in this situation, but the simulations demonstrate that the very oblique lower hybrid (LH) waves, until recently considered unimportant, may actually play a role just as significant as the waves at parallel propagation.more » The LH waves are energized by a current-driven linear instability, which may be seen as the oblique limit of the Buneman or ion-acoustic instability. The simulations resolve strong LH turbulence, substantial perpendicular ion tail heating and parallel electron heating. The combined action of parallel and oblique modes results in more complete electron relaxation than may be produced by the parallel Buneman instability alone.« less
  • The static balancing of spherical three-degree-of-freedom (DoF) parallel mechanisms and manipulators is addressed in this paper. Static balancing is defined here as the set of conditions on mechanism dimensional and inertial parameters which, when satisfied, ensure that the weight of the links does not produce any torque (or force) at the actuators for any configuration of the mechanism, under static conditions. First, the static balancing of a single body mounted on a spherical joint is studied. It is shown that it is possible to balance such a mechanism with springs, and that complete balancing can be achieved even with amore » single spring. Geometric conditions for the location of the spring attachments are given. Then, the results are applied to the balancing of the two types of 3-DoF spherical parallel mechanisms. The first mechanism is a 9R manipulator, while the second one is referred to as the 3-6-6 spherical mechanism. For each of these mechanisms, the balancing conditions are first derived for systems in which no springs are used. Then, conditions for the balancing using springs are obtained. Static balancing leads to considerable reduction in the actuator torques (or forces), which in turn allows the use of less powerful actuators and therefore leads to more efficient designs. Hence, the balancing conditions derived here are of great interest in a context of design.« less
