lems. Here, a novel unidirectional power flow control algorithm is proposed which also considers the DVR maximum compensation limit . Using this , the problems of continuous rising in dc-link voltage can be solved. Progressive phase rotating method can also be applied. In this case , it reduces compensated load voltage distortion or discontinuity. practical design considerations of the dc storage capacitor’s rating is also described. The unbalanced voltage swell compensation simulation results and analysis is also discussed to prove the effectiveness of the proposed algorithm.

determined by the frequency of the AC supply and the number of poles in the stator winding, according to the relation:

RPM = Revolutions per minute
f = AC power frequency (Hertz)
p = Number of poles (an even number)
Synchronous motors operate at the synchronous speed determined by the above equation. The speed of an induction motor is slightly less than the synchronous speed.
A 4-pole motor that is connected directly to 60 Hz utility (mains) power would have a synchronous speed of 1800 RPM:
120 x 60 = 1800 rpm

Embedded power technology is a three-dimensional, multilayer integrated packaging technology. Figure 2 shows the conceptual structure of an embedded power packaged module.

FIG 2: Conceptual structure of embedded power module
It consists of three parts: embedded power stage, electronics circuitry and base substrate, which are soldered together to build a module. The electronics circuitry (components in figure) includes gate drive, control and protection components. A hybrid (thick film) drive circuitry with high density interconnect is employed to shrink ..................[:=> Show Contents <=:]
