Protection System for High Power Inverters

Abstract

According to the title protection system for high power inverters, during the whole project work there is a focus on various modified topologies of protection and regulation system of high power inverters in industrial application systems. First of all for that, simulation of high power inverters is necessary with various topologies, some of the modifications will be done and best designing of the circuit will be done so according to the research based results of simulation, the hardware implementation of the high power inverter protection system will be developed. These topic illuminates to develop the protection system for high power inverters using FPGA(field programmable gate array) controller. The current system consist of thyristor for the high power inverters and according to the simulation results hardware implementation is done with FPGA controller board. For the reference values for FPGA code generation, one power circuit can be developed with ZCD circuit and Triggering circuit, according to the result of the power circuit FPGA controller will work in such a way that if any fault occurs in the system then the system will be protected. Parameters like power factor, harmonics, frequency variation, voltage and current ratio is maintained. Here voltage across Thyristor, Output voltage and Current waveforms are being sensed by FPGA Controller and FPGA board can be interface with the hardware and in software of FPGA program can be developed for the feedback of the protection system. FPGA developed system will consider all parameters for the protection purposes of high power inverters. However the system which can be developed in hardware or power circuit can be modify also with other power ratings and according to that FPGA controller will work and the system for the protection of the high power inverters can be easily implemented.
