Active network synthesis is important for circuit designer to find new circuits with desired performance. In this paper, a method of Tow-Thomas (TT) Bi-quad band-pass filter circuit generation methods is proposed using nullor representation of the operational amplifier (OPA), and a method for synthesizing active band-stop filters is presented, both of which start from voltage transfer function ...

This paper describes a design approach to Lorentz motors that serve as active damping component applicable in dynamic vibration isolators used for integrated circuit(IC) equipments. To satisfy the demand of high force density in constrained space and high current accuracy of motor drive for active damping, an analytical layer model with proper simplifications is employed to get preliminary dime...

High switching frequency operation in power converters leads to a significant reduction size at the cost of increased losses. Thus, soft techniques become necessary reduce WBG devices have benefit low turn-off losses, but turn-on losses are still significant. Triangular Current Mode (TCM) control can achieve zero voltage (ZVS) without adding extra resonant components or active converter. For th...

Na+-K+-ATPase and Na+/Ca2+exchange activities were studied in gills of Carcinus maenas in seawater (SW) and after transfer to dilute seawater (DSW). Carcinushyperregulates its hemolymph osmolarity through active uptake of Na+, Cl-, and Ca2+. In DSW total Na+-K+-ATPase activity in posterior gills quadrupled; Na+/Ca2+ exchange specific activity was unaffected, and total activity increased 1.67-fo...

An active-clamping quad-flyback converter is proposed to achieve zero voltage switching (ZVS) for all power switches. The secondary sides of quad-flyback converter are connected in parallel to share the load current. Thus, the transformer copper losses and the conduction losses on the output diodes are reduced. Activeclamping part including one auxiliary switch and one clamp capacitor can relea...

In this project, the operation and the features of a new three-level converter are presented with PV source and boost converter. The proposed topology was named three-level active-stacked neutral point clamped. It is a derivative of the 3L-SNPC structure, having two additional active switches connected anti parallel with the clamp diodes. The main advantage of 3L-ASNPC converter is the reductio...
