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 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..................[:=> Show Contents <=:]

es, 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 average DC bus voltage of about 650V to 680V. You can calculate this as line voltage times 1.414. The inductor (L) and the capacitor (C) work together to filter out any AC component of the DC waveform. The smoother the DC waveform, the cleaner the output waveform from the d..................[:=> Show Contents <=:]

given in table 2. As given in the table, IPEM has achieved 35% reduction of foot print area as compared to the wire-bonding version. The planar interconnects in IPEM reduces the structural inductance by a factor of three when compared to the wire bonding. But the structural capacitance is increased by a factor of five.
