. 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.

is slightly less than the synchronous speed.
Example
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
4
If the motor is an induction motor, the operating speed at full load will be about 1750 RPM.
If the motor is connected to a speed controller that provides power at 40 Hz, the synchronous speed would be 1200 RPM:
120 x 40 = 1200 rpm

Voltage induced in stator is proportional to the product of supply frequencies and area flux, if stator drop is neglected , terminal voltage ca..................[:=> Show Contents <=:]

rid winding technology. This technology is implemented using Cu traces on both sides of the winding and a dielectric layer placed in the middle to enhance the capacitive component of the winding. For this we use a high permittivity ceramic . The Transformer T2 is a conventional planar low-profile transformer.
To get the complete IPEM, we mount the active and passive IPEMs on a single ceramic chip carrier with metalization and then bonded to the heat spreader. Figure 8 shows an IPEM based DPS system and its wire bonded version.
