dynamic voltage restorer (DVR). applying conventional in-phase or phase-invariant boosting method in case of condition of swell or overvoltage, may cause a a rapid rise in dc-link voltage which may ultimately lead to the damage of the storage capacitors and switching devices, and increase the switching loss. The minimum energy injection scheme is unable to solve these problems. Here, a novel unidirectional power flow control algorithm is proposed which also considers the DVR maximum compensation limit . Using this , the problems of continuous risin..................[:=> Show Contents <=:]

cessary to change the speed of a motor That's what we'll look at next. Fig. shows a basic PWM drive. All PWM drives contain these main parts, with subtle differences in hardware and software components.
The input section of the drive is the converter. It contains six diodes, arranged in an electrical bridge. These diodes convert AC power to DC power. The next section-the DC bus section-sees a fixed DC voltage.
The DC Bus section filters and smoothes out the waveform. The diodes actually reconstruct the negative halves of the waveform onto the positive half. In a 460V unit, you'd measure an ..................[:=> Show Contents <=:]

Fig:6 Spiral Integrated LC structure
This structure consists of two windings (A-C and B-D), separated by a dielectric material. This resultant structure has distributed inductance and capacitance and is best described as an electro magnetically integrated LC resonant structure for which equivalent circuit characteristics depends on the external connections. Even more complex integrated structures can be realized by adding more winding layers.
Design of these structures requires deliberate increase and modification of naturally existing structural impedances, like intra winding capacitanc..................[:=> Show Contents <=:]
