Implementation of drive circuit for three phase inverter(Using VLSI): PWM drive circuit for three phase inverter

The three phase inverter (using MOSFETs) is designed successfully.The PWM pulses are generated using VHDL.The Field Programmable Gate Array is used.The four modes 00 to 11 are used to change the frequencies, four different frequencies are used.The readmode index 0000 to 1010 are used to change the intensity or amplitude of the frequencies. Maximum intensity will be achieved at 1010 readmode index.This is the design of Three Phase Inverter and provide the flexibility to change the frequency as well as amplitude or intensity of the circuit.These PWM pulses are used to the inverter by using IGBT also.The three inverter is very important for Agriculture field. Because most of the Agriculture pumps are run on Three-Phases.If the battery sources run on renewable energy then the Three- phase inverter is very useful.As four different frequencies are generated then this system becomes universal system because Every country they have different Mains supply frequency.
