| Abstract: | We report a cost effective high power (500 W) ferroelectric loop study set up. It has a new type of simple compensation circuit for continuous compensation of stray linear capacitance and large value resistive losses of the sample. It can be operated at continuous variable frequency modes to observe the loop structure at different frequencies. The proposed system has a drive voltage of 8400 V peak to peak and can be modified to higher voltage and higher frequencies. Instead of a loop plotter, it has a data saving facility for binary or ASCII files such that further processing of the data by computer software such as origin, excel etc can be achieved. This high power set up is suitable for a highly lossy sample. Moreover, uncompensated and compensated loop studies and time dependent loop growth observation for ceramic BaTiO3 are discussed here in.
