Focused on the current problems which exist in nine-area control strategy, such as frequent operation of control equipment and low qualified rate of voltage, the theory of nine-area method is deeply analyzed, and a new optimal setting method of reactive power interval in nine-area figure is proposed. A math model of evaluation function based on one-day energy loss of network, one-day adjusting times...
A micromechanical displacement amplifier comprising two asymmetric resonator array composites coupled by a quarter-wavelength beam has been demonstrated that permits specification of gain factor by mere (digital) selection of an appropriate ratio of the number of resonators in an input array to that in an output array. Like the method, this displacement gain circuit is a key enabler for resoswitch-based...
This paper analyses and designs a zero-current-switching single-phase high power factor voltage-doubler rectifier. The proposed rectifier combines the conventional pulse-width-modulation technique, soft commutation technique and instantaneous average line current control to promote the circuit performance. Comparison with conventional boost rectifier, the proposed rectifier own double voltage function...
The resonance and nonlinear dynamical properties of micromechanical structures have been harnessed to demonstrate an impacting micromechanical switch with substantially higher switching speed, better reliability (even under hot switching), and lower actuation voltage, all by substantial factors, over conventional RF MEMS switches. The particular resoswitch implementation demonstrated in this work...
