ultrasonic vibration assisted single point incremental forming (uvaspif) process is an attractive and adaptive method in which a sheet metal is gradually and locally formed by a vibrating hemispherical-head tool. the ultrasonic excitation of forming tool reduces the average of vertical component of forming force and spring-back rate of the formed sample. the spring-back phenomenon is one of the...

This work studies a full-power, module-integrated back-to-back converter for battery energy storage applications. The proposed solution optimizes bank usage across wide range of individual capacities. design and control are examined, as well the use loss reduction method when operating under partial load. suggested architectural allows to have regulated voltage output, simulating passive bank, ...
