Electrical viva questions on this project
What is the aim of the Vertical Axis Wind Turbine With Inverter project?
A vertical-axis wind turbine that charges a battery and powers AC loads through an inverter. An ATmega328 manages charging and shows the generated voltage on an LCD.
Explain the working of your project in short.
12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V. The Push buttons and switches provide manual inputs and the power switch. The ATmega328P microcontroller with base board is the brain of the circuit: it samples the sensors, compares readings with set limits and switches the outputs. The 16×2 LCD with I2C adapter shows readings, status and messages to the user.
Why is a microcontroller used in this project?
A microcontroller combines a CPU, memory and I/O pins on one chip, so a single low-cost IC can read sensors, make decisions in code and control loads without a computer.
Why is a pull-up resistor needed with a push button?
Without it the input pin floats and reads random values. The pull-up keeps it HIGH until the button connects it to ground.
Why is an I2C adapter used with the LCD?
It reduces the wiring from about 10 pins to 2 (SDA and SCL), leaving more controller pins free for sensors.
Why is a resistor connected in series with an LED?
It limits the current to a safe value (about 10–20 mA). Without it, the LED would draw too much current and burn out. R = (supply voltage − LED voltage) ÷ current.
How is 230 V AC converted to 5 V DC for the circuit?
A transformer steps down the voltage, a bridge rectifier converts AC to pulsating DC, a capacitor smooths it and a 7805 regulator gives a steady 5 V.
How did you calculate the power rating of your system?
Using P = V × I for each load, adding a margin of 20 to 25%.
What protection have you provided in the circuit?
A fuse against short circuit, relays or optocouplers to isolate the control side from the power side, flyback diodes across inductive loads such as relays and motors, and software limits that cut off on over-current or over-voltage.
What is the efficiency of your system and how did you measure it?
Efficiency = output power ÷ input power × 100. We measured input and output voltage and current with a multimeter at different loads and tabulated the results in the report.
Explain the block diagram of your project.
The input section senses the real-world quantity, the ATmega328P microcontroller with base board processes it according to the program, and the output section displays the result and drives the actuators. The power supply section feeds every block.
