Comparison Analysis of Semiconductor Characterisation topologies using Energy Recirculation Concept

Abstract

Energy recirculation concept in semiconductor device characterization can increase power handling capacity of the source and it will reduce naturally existing high electrical stresses on device under test. The proposed energy recirculation and storage circuits (ERSC) can be employed as a device in-situ testing unit, by storing and recirculating the energy of the storage elements. ERSC enables devices to be checked at full-power pressures without being attached to a high-power load or requiring high power source. ERSC has four active states of operations achieved by the two active switches of the proposed converter. This converter can function in four different modes of operation, namely - soft start, magnetize, charge, and energy recirculation modes. Another advantage of this converter is that the two circuits can be constructed to work synchronously or asynchronously, allowing for the testing of faster or slower devices depending on the performance of the device being tested. In this paper double pulse test, single ended buck boost and cascaded boost -buck ERSC converters are simulated using MATLAB/SIMULINK and based on the results cascaded boost-buck ERSC having better performance compared to existing testing methods.
