La‐ and Sn‐cosubstituted lead zirconate titanate () ceramics are synthesized using a solid‐state reaction route. These (PLZST) ceramics in pure form are found to exist in dual phase () and single phase (Cc) depending on the amount of La/Sn cosubstitution. PLZST ceramics exhibit thin P–E loops with enhanced polarization when measured at 393 K. Olsen cycle method is used to estimate the pyroenergy harvesting abilities of the samples under study. The estimated maximum energy storage density for PLZST () ceramics at 393 K is 1.16 J cm−3 [efficiency (η) > 96%]. The PLZST ceramics exhibit a remarkable hardness of 9.08 GPa. These results indicate that PLZST ceramics with excellent multifunctional properties are potential candidates in the field of electroceramic devices.

Nowadays, Renewable Energy Sources (RES) integration to Distribution Systems (DS) by employing latest Power Electronic Converters (PEC) is highly increased. This paper presents, a new grid connected / interfacing inverter control organization for a 3-Ø 4-wire DS. The implemented inverter is incorporated with Active Power Filter (APF) functionality which can control and perform as a multi-functional device. So, the inverter is operated as both power converter and Shunt APF as well. The power converter function is to inject the real power into the grid, whereas the shunt APF is to minimize reactive power demand, current harmonics and unbalance current. With the effective inverter control scheme, the 3-phase 4-wire DS at PCC seems as balanced load to grid. The inverter and its control scheme are implemented in using MATLAB /Simulink environment.
