Ti element is found to aggregate, forming an ultra-fine reaction layer in the active filler metal-ceramic joint after 260℃/24hr aging treatment. Two different-color intermetallic compounds are observed in the interface of active filler metal-copper. One is Cu6Sn5 , which is closer to active filler metals;the other is Cu3Sn, which is closer to the copper substrate.

The principle of the novel single-phase hybrid active power filter is described in detail. Based on the above analysis, Kalman filtering approach for estimation of harmonics is presented to improve the speed and precision of harmonic detection, and it also can avoid the influence made by voltage distortion on harmonic detection. A new current control strategy based on energy balance is presented to regulate the active part absorbing or releasing active power and control the inverter to produce current opposite to the harmonic current reflowing in injection branch, the above method combined with harmonic current tracking control that keeps the stabilization of dc-side voltage and improve the reliability of the system.
