Design & Analysis of DC to AC Three Phase Inverter
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryThis project deals with study of a Sinusoidal Pulse Width Modulated Inverter and all the parameters used to reduce the harmonics and give the good efficiency of the inverter. The project will be commenced by a basic understanding of the circuitry of the SPWM Inverter, the components used in its design and the reason for choosing such components in this circuitry. Generally, only single phase SPWM inverters are used industrially, and certain instabilities have been found in their operation. With improper selection of system parameters, the inverter suffers different type of instabilities and many types of harmonics. Our attempt will be to observe the same for three phase SPWM inverter and analyze its parameters used to get a pure sinusoidal output waveform and fewer harmonic in its output current and voltage waveform. Three phase inverters are essential in many industrial applications for providing adjustable-frequency power.
Project Objectives- Backup power for industry
- Speed control of three phase machinery.
- Sinusoidal Alternating Currenting
Sinusoidal pwm is generated to form a pure sine wave ac. this will reduce harmonics. transfomer is used to step up the voltages.
Benefits of the Project- Inverter will reduces the damages to the equipments
- Pure AC sine wave is obtained
- Speed can be controlled be varing frequency
Sinusoidal PWM is generated to form pure sine wave alternating current. DC power is suppled to switches. AC current is step up by using transformer. Speed can be controlled by changing the frequency.
