Description
This project attempts a soft start control technique for the single-phase a.c. induction motor. The circuit operation is controlled by an 8051 family microcontroller.
The device is aimed at substituting the commonly used triac phase angle control drives. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage during start. Same as in triac control, the voltage applied to the load is varied from zero to maximum value in a small span of time during start. The circuit is capable of supplying a single-phase a.c. induction motor (or general a.c. inductive/resistive load) with varying a.c. voltage at the start. It uses a pulse width modulation technique (PWM), and when compared with the phase angle control used for triacs, it produces much lower high order harmonics. It directly modulates the mains a.c. voltage. Thus, it suits EMC/EMI regulations much better. Because the circuit is aimed at low-cost, low/medium-power applications, it does not use a conventional converter topology to produce the output voltage waveform. Compared with costly converter, it requires a lower number of active and passive power components. The drive uses a PWM controlled MOSFET and the load in series with a bridge rectifier. The device attempted here takes advantage of both the low price of the phase angle control and the low harmonic content and high efficiency that we can get with standard converter topology. This drive based on this new control technique is targeted for use in consumer and industrial products: washing machine, dishwashers, ventilators, compressors.
Note
Soft start of induction motor using acpwm this project for the good price for the engineering projects. It is very comparative engineering project. It is very good project BE power electronics project student is use. For the project is the embedded base project and core electronics base project. This project is electrical based project,
Soft start of single phase induction motor is the microcontroller based project for the good project, excellent project for the BE last year engineering student is use for the student is use core electrical student is use. This project for the competitive project in the BE electrical based project of the last year engineering student for the core electrical is use.
The engineering projects give in the ELECTROSAL HI- TECH PVT.LTD. The best place of the degree and diploma final year engineering projects as well as electrical student is use. This project is power electronics based project and microcontroller based project.
Soft start of single phase induction motor the best projects of the embedded base for the power electronics ,in final year student is use and idea for the and degree and diploma base students and 100% output is done.
