This paper presents a differential current compensation technique for partially shaded PV string. The proposed technique integrates an input parallel output series (IPOS) configuration of DC-DC flyback converters with distributed digital voltage mode control. PV modules in the string are interfaced with IPOS configuration of flyback converters. Each dedicated converter is regulated at the MPP voltage...
The high power density of Supercapacitors (SCs) make them good elements for Hybrid Energy Storage Systems (HESSs). In order to increase the amount of energy of their high power bursts, they should operate with large voltage variations. This paper presents the design equations of a 3-switch bidirectional DC-DC converter with a tapped inductor that can be used for interfacing SCs to DC buses. Some of...
This paper presents Finite Element Method calculation and measurement results of a permanent magnetic excited transverse flux machine designed as shoulder joint motor in an articulated six axis robot arm in service robotics. The transverse flux machine prototype with its claw pole stator and its external rotor with surface mounted permanent magnet, as well as the whole test bench setup is presented...
