Generation of PWM using verilog In FPGA

Abstract

In this paper a new approach of generating the Pulse width modulation (PWM) signals which are to be used in various power electronics application like power converters and inverters is presented. Pulse Width Modulation (PWM) triggers the gate terminals of the power electronic semiconductor devices like thyristors, Insulated-Gate Bipolar Transistors (IGBTS), Metal Oxide Semiconductor Field Effect Transistors (MOSFET) etc. which are used as switches for voltage regulation. The pulses are generated using hardware description language (HDL) which is suitable for usage in Spartan-3E Field Programmable Gate Array (FPGA) board which is used as high performance controller in vector control of induction motor. Simulation is done in Model Sim 6.2b environment and results are obtained validated with register transfer level (RTL) schematic.
